Sex was God’s idea.

Sex was God’s idea.

Start here, because everything in this framework is built on this foundational principle.

The most important thing the Bible says about sex is said in Eden, at the dawn of creation and before the fall. Simply, that sex is very good, and we also learn that God made it on purpose.

Created good, and “very good”

In Genesis, God makes humanity male and female, and He tells them to “be fruitful and multiply.” Basically, have sex. God looks at the Adam and Eve, their bodies, their difference and their desire and calls it very good (Genesis 1:27–31). The first command involves having sex, be fruitful and multiply, is not a prohibition. It’s a blessing. Sex is not a regrettable necessity God tolerates; it’s part of a creation He made and delights in.

“One flesh” (union before the Fall)

There are two things to notice here:

First, one flesh is covenant language. Sex is the bodily sign and seal of a whole-life union, a covenant. It is not a recreational add-on.

Second, they were naked and not ashamedand that this is God’s original design. This is complete exposure, complete safety, zero shame. Much of the practical work of a good sex life seems to be recovering, inside a committed covenant, that lost “naked and unashamed” state of being.

God put erotic poetry in the Bible

The Song of Songs is an entire book of Scripture that is a frank and sensory celebration of romantic and sexual love between a husband and wife. Their bodies, their longing, their desire, their delight in each other are all described. And this is not primarily an allegory you have to spiritualise away because, at its plain level, it is God endorsing married desire as beautiful.

These are not a euphemism for something more respectable. God is for great, covenanted sex.

The three purposes of sex

Scripture gives sex more than one God-given purpose, it gives us a trinity of them:

1. 01Union / oneness. Sex makes and renews the “one flesh” bond. It is the covenant being seasoned with bodies. If we can put it this way, sex is to the marriage what bread and wine is to the church.
2. 02Pleasure and delight. The Song of Songs and Proverbs 5 make clear that mutual enjoyment is a goal in itself, not a lucky by-product. For some reason the church has under-taught this; the books on our list spend a lot of energy redeeming this idea.
3. 03Procreation. Children (where God gives them) come from sex. But crucially, procreation is not the onlypurpose of sex. A couple who can’t or don’t conceive are not having “lesser” sex. The Song of Solomon never actually mentions children as it focuses entirely on romantic love, physical intimacy, and emotional devotion for their own sake.

Great sex is when we hold all three loosely together. Distortions almost always come from collapsing sex into onlyone purpose — only procreation (so pleasure is suspect), or only pleasure (so it’s detached from covenant), or only union (so the body and its delight get spiritualised into nothing).

Sex as “knowing”

The Hebrew Bible’s word for sex is often yada, which means to know.

That’s not prudishness; it’s a profound revelation into what sex is about. Sex is meant to be both deeply personal and a mutual knowing. It is a way of being fully seen and fully accepted, body and soul. Great sex is great knowing— so technique serves intimacy; it never replaces it.

Sex happens in front of God (and that’s the best news, not the scariest)

We tend to picture God as the policeman at the bedroom door, not happy about anyone coming in and begrudgingly letting your spouse in. But He is not the inspector of this gift; He is its inventor, and He is for it.

On the inside of marriage, sex becomes a kind of worship so every time, the two of you say again with your bodies what you once said at the altar: I am yours, you are mine, no one else.It is the covenant remembered and re-signed — often done in remembrance of the covenant you made.

That is why the culture’s idea of sex as conquest, something you collect to prove something about yourself, is so thin beside the biblical vision of sex as covenant, something you give to seal a promise.

And, on the outside of marriage, that same presence is what makes faithfulness matter even when no one would ever know what goes on behind closed doors. If Someone is always in the room, then purity was never mainly about not getting caught. The question underneath a faithful sexual life is not who would find out? It is who is already here?

Clearing the rubble (things to unlearn first)

The Great Sex Rescuecovers this idea a lot, and it matters because for a lot of people the obstacle to a good sex life isn’t a lack of technique — it’s bad teaching they absorbed in church, in youth group, or in popular Christian books. You can’t build well on rubble. Some Christian ideas need to be actively put down.

The obligation / “duty sex” message

The teaching that a wife (it’s almost always aimed at wives) must always be sexually available so her husband won’t stray, or to fulfil a duty, regardless of her own desire or pleasure. In Great Sex Rescue, Gregoire’s research found this message correlates with worse outcomes like lower arousal, more pain, less satisfaction, and, painfully, with feeling used.

1 Corinthians 7 is mutual, not one-directional.

In a culture where a wife was property, Paul says the husband’s body equally belongs to his wife. The point is mutual self-giving, not leverage. Sex is something you give to each other, never something you are owed and extract.

The “every man’s battle / men can’t help it” framing

The message that men are helpless before visual temptation and women are responsible for managing male desire (by covering up, by always being available, etc.). This is bad for everyone as it infantilises men, makes women the sin-police, and teaches us that lust is unstoppable rather than something the Holy Spirit actually helps put to death.

We would say that men are responsible for their own eyes and hearts. No excuses.

Purity-culture shame

Purity culture was one of those things that had good points and bad points. One of the bad points was that many people spent a decade hearing that their sexuality was a danger to be suppressed, “don’t, don’t, don’t”. But then on the wedding night, they were expected to flip a switch into “do, joyfully.” It doesn’t always work like that. Shame doesn’t evaporate at the altar and it can follow people into the bedroom. Naming this is half the cure. The body and its desires are not dirty. A married couple has nothing to be ashamed of.

The “gatekeeper” myth and the lie that sex is mainly for men

Lots of teaching frames sex as something men want and women dispense. Reality and the Song of Songs say otherwise as the Song’s most ardent voice is the woman’s. Women’s desire and women’s pleasure are not afterthoughts (see the point on the clitoris below). A marriage where only his pleasure is the point isn’t biblical sex, it’s men being selfish.

Spiritual performance pressure

The flip-side error in some Christian books is turning sex into another arena to perform with frequency targets, the wife who must always initiate enthusiastically and the implication being that godly couples have constant fireworks. This just relocates shame. Watch out for this, too.

The foundations of great sex (what actually makes it work)

Every author on our list all have the same principles that they keep coming back to. These matter more than technique, and technique without them falls flat.

1. 01Mutuality. Both people’s experience counts equally. The aim is not “his satisfaction” or “her satisfaction” but ours. This is the practical outworking of 1 Corinthians 7.
2. 02Emotional safety and trust. You cannot be “naked and unashamed” with someone you don’t feel safe with. Sexual intimacy grows out of the wider relationship, so how you speak to each other at breakfast affects what happens at bedtime. For women especially, feeling emotionally connected and safe is often the gateway to physical desire, not the reward for it. Build the relationship and the bedroom follows.
3. 03Communicate out loud, with words. This is the single most practical skill for great sex. Couples routinely guess for years rather than say plainly what they enjoy, what they’d like more or less of, what hurts. None of the books treat your spouse as a mind-reader. Learning to talk about sex kindly, specifically and without blame, is the highest-leverage thing most couples can do. “I love it when you…”, “Could we try…”, “That’s a bit uncomfortable, can we…”. It feels awkward; do it anyway.
4. 04Both pleasures matter (closing the orgasm gap). There is a well-documented orgasm/pleasure gapin many marriages, where his pleasure is treated as the default endpoint and hers as optional. Gregoire’s data ties this directly to lower marital and sexual satisfaction. Closing it isn’t selfish or “secular” it is thinking about mutual pleasure.
5. 05Time, attention and non-haste. Good sex usually isn’t fast. Arousal, especially female arousal, takes time and unhurried attention. Couples who protect time for each other, who don’t treat sex as the last item on an exhausted to-do list, do better. This is a scheduling and priorities issue as much as a bedroom one.
6. 06Playfulness and freedom. Within the marriage, there’s enormous freedom (Part 10). Couples who can laugh, experiment, and not treat every encounter as a performance evaluation tend to thrive. The Song of Songs is playful. Take sex seriously, especially the pleasure of your spouse, but at the same time, don’t take yourself too seriously — enjoy the playful side too.
7. 07Repair and forgiveness. Nothing kills desire faster than unresolved resentment. The bedroom is the barometer of the whole marriage. You cannot snipe at each other all day, leave the hurt unaddressed, and expect the body to switch into closeness at night. Many “sexual problems” are really relational problems wearing a sexual disguise. So learning to repair quickly, to apologise, to forgive, and to refuse to let the sun go down on anger (Ephesians 4:26) isn’t separate from your sex life; it’s part of it. Sometimes the most important foreplay is a sincere “I’m sorry.”

Understanding the differences between you.

A recurring theme is that a lot of marital friction around sex is just two people who are built and wired differently assuming the other is being difficult. Understanding the differences defuses most of this friction.

Arousal speed and pattern

Generalising (individuals vary enormously) brings you to the idea that men often arouse quickly and visually; women often arouse more gradually, and through touch, words, emotional connection and context. Treating the faster pattern as “normal” and the slower as “broken” is a classic mistake. Neither is the standard. The practical upshot is foreplay and unhurried attention are not optional extrasas for many women they’re the main event of arousal, not the warm-up.

Spontaneous vs responsive desire

This is one of the most freeing concepts for couples as some people experience spontaneous desire which is wanting sex “out of nowhere.” Whilst others (more often, though not only, women) experience responsive desire where they don’t feel much wanting until arousal has already begun. In other words, desire shows up in response to closeness and stimulation rather than before it.

Neither is dysfunction.

A huge number of couples wrongly conclude “she’s just not interested” when in fact she has responsive desireand is waiting for an initiation and a warm-up that never actually arrives, or arrives too fast. Knowing this can rescue a lot of marriages from a false “low libido” diagnosis.

Desire discrepancy is normal

Almost every couple has a higher-desire and a lower-desire spouse, and it can be either of them. Don’t make the assumption that it’s always the husband that has the higher desire. The goal is not to shame the lower-desire spouse into compliance (rubble — Part 2) nor to leave the higher-desire spouse chronically rejected. It’s to find, by honest conversation and mutual care, a shared rhythm that honours both. This is negotiated together, lovingly, over time.

The role of context and load

Stress, exhaustion, small children, body-image, hormones, mental health and medication all materially affect desire and arousal for both spouses. This isn’t an excuse; it’s reality. Couples who account for it (protecting rest, sharing the domestic load, being patient through seasons) do better than couples who treat desire as a pure matter of willpower or love.

The practical mechanics.

Here, we want to avoid being coy (as is the Christian way) and so will use clear sexual language.

Know the body — both bodies

A surprising number of couples struggle simply because no one ever taught them basic anatomy. The most important thing to know is that for the large majority of women, orgasm comes primarily from clitoral stimulation, not from intercourse alone.

This is not a flaw or a worldliness to be embarrassed about in any way. It’s how God designed female anatomy, and the clitoris has no function otherthan sexual pleasure, which tells you something about God’s intentions.

Couples who learn this, and build it into how they make love rather than treating intercourse as the only “real” act, routinely close the pleasure gap described in Part 3.

Foreplay is not a preliminary; it’s central

Unhurried touch, kissing, words, building arousal gradually and for many that have responsive arousal, this is the path to both desire and orgasm, not the run-up to the “main” event. Generosity and patience here is the loving thing to do.

Arousal, lubrication and comfort

Adequate arousal matters physically and not just emotionally. For many women, sufficient arousal and lubrication make the difference between pleasure and pain. Where natural lubrication is low (common with stress, breastfeeding, menopause, certain medication), a simple lubricant solves a great deal and is entirely fine to use.

Variety, initiation and who leads

Within the marriage, there’s freedom to vary positions, timing, who initiates, where and how. Variety keeps things alive over decades; routine is the slow enemy. Both spouses initiating (not just the husband) is healthy and, per the Song of Songs, biblical. Remember, her desire is meant to be expressed, not suppressed.

Frequency (drop the magic number)

There is no biblical “should” for how often. The healthy frequency is the one a particular couple lovingly negotiates so that the higher-desire spouse isn’t chronically deprived and the lower-desire spouse isn’t chronically pressured. Comparison to imagined averages can easily breed discontent.

Orgasm (aim for mutual, not simultaneous)

Chasing simultaneous orgasm as the gold standard creates needless pressure and disappointment. Most couples find it easier and more satisfying to attend to each person’s pleasure in turn. Orgasm is a wonderful gift but not the sole scorecard; connection, closeness and mutual delight are the point. Some encounters are fireworks; some are quiet and tender; both are “real” sex.

Protect the conditions

Practically, ensure that you guard time and energy for each other, deal with the relationship out of bed, keep the bedroom a low-pressure place, and keep talking. Mechanics serve intimacy, never the other way round.

Common difficulties (and how to approach them)

Almost every couple hits a sexual difficulty at some point. The shame around it is usually worse than the problem. Naming the difficulty, as Wheat, Rosenau and the Penners (especially Restoring the Pleasure) do, is 80% of the battle.

Mismatched desire

This is the most common difficulty. The approach is to name it without blame; identify whether responsive-vs-spontaneous desire is being misread (Part 4); look at context and load; negotiate a rhythm together; and have the higher-desire spouse pursue connection, not just sex. If it’s entrenched, a counsellor helps.

What the higher-drive spouse shouldn’t do is keep mis-quoting 1 Corinthians 7 (see Part 2).

Pain during sex (for women)

Real, common, and not“in her head” or something to push through. Causes range from insufficient arousal/lubrication, to vaginismus (involuntary muscle tightening), to medical conditions. Pain is a signal to stop and address the cause, never to endure silently, and the old “just push through it as a duty” advice is exactly the rubble that does damage. The Wheats and Penners give practical, graded approaches; persistent pain warrants a doctor and often a Christian sex therapist or pelvic-floor physiotherapist.

Erectile and arousal difficulties (for men)

It’s more common than you think, especially with age, stress, anxiety, or health/medication. Performance anxiety doesn’t help at all. The approach should reduce pressure, address physical health (it can be an early flag of other issues, so worth a visit to your GP), and treat it as a shared thing to work through, not his private failure.

Difficulty reaching orgasm

Often an arousal, technique, or anxiety issue rather than anything broken and is frequently solved by the anatomy and foreplay points in Part 5, plus reduced pressure. The Penners’ structured exercises are designed for exactly this.

The wedding-night / early-marriage gap

Couples who waited for their wedding night often expect instant ease and feel ashamed if it’s awkward. It is almost alwaysawkward at first. It’s a skill you learn together over months and years. Remember this in advance of your wedding as it removes a lot of needless distress.

Initiation, and the pain of being turned down

A common wound in a marriage is that one spouse does most of the initiating, gets turned down often enough, and slowly stops trying, not from indifference but from self-protection.

Rejection is felt deeper here, because you’re not offering a favour, you’re offering yourself. Two things can help. For the one who initiates less, remember that a “no” to sex tonight is not a “no” to them, so say it warmly, offer a real “not now, but soon,” and don’t let a refusal land as contempt. For the one who initiates more, don’t let each “no” harden into a tally you hold against them, and never withdraw affection as a punishment. The Penners and Rosenau both treat this as a skill couples can learn, not a verdict they’re stuck with.

When to get help

Persistent pain, persistent dysfunction, desire that has flatlined for a long season, or sex that’s become a source of conflict or dread — these are reasons to see a GP and/or a qualified (ideally Christian) sex therapist or counsellor. Seeking help is wisdom, not failure.

Sex through the seasons (children, ageing, and the long arc)

A lot of disappointment in Christian marriages comes from the false assumption that sex is meant to stay like the honeymoon, and that if it changes, something has gone wrong. It’s meant to change. A marriage is decades long, and the bed travels through every season the rest of life does. Knowing that in advance saves a great deal of needless grief.

The seasons are real, and normal

There are seasons where you’re still learning each other; through pregnancy and the bone-tiredness after a baby; in the years when small children leave nothing in the tank; through illness, grief, stress and the slow changes of middle age, when frequency and energy simply bend. None of that is failure. The goal in a hard season isn’t to keep the old pace but to stay close in the ways the season allows, gently and creatively, without turning intimacy into one more thing to perform.

Pregnancy and the postpartum desert

Bodies change, desire changes, and after a birth there can be a long recovery, exhaustion, hormones, a body that has felt claimed by someone small all day, so a wife may have little left for sex. This is not rejection and not permanent. Patience, low pressure, and closeness that isn’t only intercourse carry a couple through. (A simple lubricant helps with the dryness that’s common while breastfeeding — see Part 5.)

Ageing, menopause, and the body that shifts

Desire, arousal and response all change with age, for both spouses. Menopause can bring dryness and discomfort that are straightforwardly helped; men’s arousal slows and becomes less automatic. None of this is the end of a couple’s sex life but it is a new chapter that often trades urgency for tenderness. The couples who do well keep talking and keep adapting, rather than mourning the old normal.

Illness, disability and limitation

Sometimes a body can’t do what it once did, whether through illness, injury, disability or medication. In such cases, sex has to be reimagined, intimacy redefined around what’s possible. That’s hard, and maybe worth grieving but it’s also survivable, and many couples find a deeper closeness on the other side of it. Here more than anywhere, tenderness and presence matter more than performance.

The long view — the well that runs deep

Our culture can’t picture good sex in old age; it only believes in the young. Scripture has a different viewpoint: “rejoice in the wife of your youth… be intoxicated always in her love” (Proverbs 5:18–19). This is written about a love meant to last past youth. It is a well that runs deep, that a couple is still drinking from decades in. The honeymoon is the start of the story, not its peak.

The question of children, contraception and family planning

Couples rightly ask how the procreation purpose (Part 1) fits with planning a family, and here Christians genuinely differ. The Catholic tradition holds that sex should stay open to life in each act, and so favours natural family planning over artificial contraception. Most Protestant and evangelical Christians see contraception as a matter of wisdom, freedom and good stewardship, to be used prayerfully to space or plan a family. They still hold children as a blessing to be welcomed, not merely a risk to be managed. Wherever a couple lands, the heart-questions are the same: are we welcoming children as a gift, are we deciding this together, and are we trusting God with the family He gives us?

When children don’t come (infertility)

For some couples the longing for children meets the grief of infertility, and that can quietly reshape the marriage bed. Sex may turn clinical, scheduled, monitored, pressured, drained of joy and freighted with disappointment month after month. This is one of the deepest aches a marriage can carry, and it is a grief, not a failure of faith.

A couple is no less married, and their sex no less good and complete, for being childless. The Song of Songs never mentions children. And it helps enormously to deliberately keep some intimacy un-clinical: to protect lovemaking that isn’t about conceiving, so the bed doesn’t become only a means to an end.

For those who have suffered miscarriage or infertility, please visit our page on miscarriage and baby loss.

When sex is tangled with wounds.

This part comes with the most care, because for a real number of people in any church, sex is bound up not with technique but with past abuse, assault, or trauma, so a chirpy how-to book can wound rather than help. This is where the Holcombs’ Rid of My Disgrace is essential reading.

The disgrace is not yours

What was done to you is not sin you committed, and it does not define you or your worth before God. Shame says “I am dirty / ruined / unlovable.” The gospel says the opposite because Jesus took the disgrace, and you are clean, beloved, and not at fault.

Disgrace

Trauma changes the body’s responses

Survivors may experience flashbacks, freezing, dissociation, or pain during sex even in a safe, loving marriage. This is the body remembering, not a failure of love or faith. It is not fixed by “trying harder” or by a spouse pushing. Patience, safety, and often professional trauma-informed therapy are the path.

For the spouse of a survivor

Your job is safety, patience and gentleness. Never pressure. Going slowly is love. This is one of the clearest places the “obligation sex” teaching does real harm, and must be firmly set aside.

Past sexual sin and shame (a different but related thread)

Many carry guilt over their sexual past. The gospel is that in Christ there is full forgiveness and a clean slate (1 John 1:9; 2 Cor 5:17). Past experience can leave comparisons, habits, or shame that need honest work, but it does not disqualify anyone from the good gift of sex within marriage.

Pornography

Porn is so common and so corrosive to intimacy. It trains people toward fantasy, performance and consumption, which is the opposite of the mutual, embodied covenant knowing sex was made for. It erodes real closeness and creates huge drive, arousal and desire problems for a couple.

Handle porn as something both to heal and to battle, never merely to be ashamed of.

When the harm is happening now (a hard, necessary word)

Everything above assumes the wound is in the past. Sometimes it isn’t. If sex in your marriage is coerced, if you are pressured, threatened, guilted or forced, if “no” is not allowed to mean no, that is not a rough patch or a libido mismatch. It is abuse, and being married does not make it something else.

“The marriage bed is undefiled” was never a licence to take; 1 Corinthians 7 is mutual self-giving, never one person’s claim over another’s body. If this is your marriage, please tell someone safe like a pastor, a trusted friend, a professional, and know that your safety matters to God far more than keeping up an appearance.

The battle for purity.

Sex is a gift. And like any good gift from God, it needs to be guarded, because it can so easily be twisted into something it was never designed for — and that is true for all of us, whether you’re married or single. But for a long time, Christians have been fighting this battle with tactics that don’t really help. There has to be more than just gritting your teeth and taking lots of cold showers.

The body is good

One way we’ve tried to deal with this is to carry around the idea that the body is bad. And this matters enormously, because if the bodyis the problem, the answer becomes covering up, looking away from the world, treating attraction itself as sin. But nothing about the body changed between “naked and not ashamed” in Genesis 2 and the shame of Genesis 3. The heart changed. Skin was never the problem.

What’s interesting is when Jesus talks about lust, He didn’t say it’s about what you see being the problem. You are a person with eyes full of wonder in a world full of people. The problem is in the cultivated second look, “looking with lustful intent” (Matthew 5:28) that is the issue. And that’s a heart issue. And it’s an issue directed at the person who is looking, not the person being looked at.

There’s an old picture, usually pinned on Luther, that you cannot stop a bird flying over your head, but you can stop it building a nest in your hair. The first look is the bird. The nest is the choice to dwell on an idea and image in your mind. Naming this frees people twice: first from shame about simply being attracted, and secondly from the confusion about what actually needs to change.

You don’t beat lust by wanting nothing, you beat it by wanting something more. This is what the “just bounce your eyes, try harder, install the software” approach can miss. Whilst all of these things are good and worth doing, we have to get to a place where we realise that willpower on its own runs out. A heart is never a vacuum so you cannot scrub a desire out of it, but you can replace it with a greater one. (The old preachers called it “the expulsive power of a new affection”; Lewis pictured a man’s whimpering lust put to death and rising as a great horse that carries him up the mountain — so the desire not destroyed but redeemed.)

God is not working to make you someone who wants nothing. He is working to make you someone whose wanting has somewhere glorious to go. Purity, in the end, is less stop looking there and more start looking here, at a God more satisfying than anything a screen ever showed you. And this is as true for the single person with no outlet as for the married one. The answer to misdirected desire is never a switched-off desire; it’s a rightly-aimed one.

Pornography

Porn trains us to see a performance, a thing made for us. But the person on the screen is somebody’s son or daughter, as real as your own. You cannot know whether she chose to be there or was lied to, coerced, or trafficked (some, it has been proven in court, were exactly that).

Porn isn’t only self-harm, though it is that. Porn trains you to take, in private, from someone you will never have to face — which is the exact opposite of the mutual knowingsex was made for. It is also a sin against your neighbour, the person on the screen who needs Jesus, who has been made in His image and is precious to Him. The shift from “is this hurting me?” to “this is a person God loves here” does more to loosen porn’s grip than willpower alone.

A word on masturbation

People ask about this more than almost anything, and the honest answer is that faithful Christians land in different places on the topic. We would say that Scripture doesn’t seem to address it directly (but acknowledge there are passages that people believe do; we would interpret them differently). So we want to be slow to bind a law the Bible doesn’t seem to give us.

The book The Gift of Sexis helpful here, as talk of self-stimulation can bring about anxiety, fear or even disgust depending on your thoughts about the topic. All kinds of falsehoods have been said about it, from “you will get warts” to “you will go blind”, that make it feel wrong or dirty.

Every boy, and a slightly smaller percentage of girls, have engaged in the act of masturbation. So the church has to be more than “just don’t do it”. That’s not a free licence, by the way — the normal rules of lust, not watching porn etc, still apply.

The authors identified four areas that we should be concerned about:

1. 01Experiencing oppressive guilt, especially if growing up in a Christian environment that teaches masturbation is wrong. The practice was unlikely to stop, so feelings become associated with guilt, which leads to a high vulnerability to premarital sex and extramarital affairs.
2. 02When masturbation becomes obsessive. Dr James Dobson in Focus on the Family says that “the best way to prevent that kind of obsessive response is for adults not to emphasise or condemn it.” It’s also known that oppressive guilt (1) leads to obsessive practice.
3. 03When it is fuelled by fantasy or pornography. People who masturbate in response to porn easily create an addiction and the destructive loop of needing more and more hardcore porn to reach orgasm. This is the very thing Jesus talked about with lust — the image, taking in the mind what was never yours to take.
4. 04When masturbation is brought into a marriage as a substitute for sex between husband and wife. If it’s used as avoidance of contact with your spouse, then this is contrary to 1 Corinthians 7:3–5, as we are to give ourselves to each other.

So the most useful question is rarely “is masturbation wrong?” but “what is it feeding, and what is it feeding on?” Self-stimulation is a way of discovering your own body and what creates satisfaction, which can be communicated to your spouse and can be helpful in marriage.

We don’t agree that masturbation is always driven by lust (but for many it is). Also, if it is driven by fantasy, escape, compulsion, or a way of medicating loneliness or numbing out, then it’s discipling your heart in the wrong direction. The goal here, as everywhere in this part, is freedom and a rightly-aimed desire — not a streak you’re white-knuckling, and not a shame-spiral every time you fall.

Bring it into the light

Sexual sin lives on secrecy; it is strongest exactly where no one can see. So the single most practical move is also the hardest thing, because you have to drag it into daylight. Name it to God and then — the part people skip — name it to one trusted person. Not the whole church, not the internet. One safe friend, mentor or pastor. The moment a hidden thing is spoken out loud in front of God and one other human, it begins to lose its grip. This is confession, and it is how the battle is actually won.

When it’s more than a struggle

One important caveat to all of the above. Sometimes this has stopped being an ordinary fight and become a genuine compulsion, something with its hooks in deep, that you’ve tried to stop a hundred times and can’t. It keeps escalating, or hiding, or wrecking things you love. That isn’t a failure of willpower to try harder at; it’s closer to an addiction, and addictions are rarely beaten alone with a covenant and good intentions. There’s no shame in it and real hope for it, but the route is structured help that often involves a recovery group, a counsellor, sometimes a programme built for exactly this. Bringing it into the light is the first step; for some people it needs to be the first of several.

“What’s actually allowed?” (the boundaries question)

People ask this a lot. As humans we want to know where the boundaries are, and sex is no exception. Be careful of asking that just because you want to see how far you can go (that always leads to you going further than you should). Boundaries here are not lines to be pushed. They are safeguards intended to keep us in a good place.

What Scripture clearly states. The Bible is consistent that sexual intimacy belongs within the covenant of marriage between a husband and wife, and it clearly rules out:

• Adultery— sex outside the marriage (Exodus 20:14; Hebrews 13:4).
• Sexual immorality (porneia)broadly — sex outside marriage’s bounds (1 Cor 6:18; 1 Thess 4:3–5).
• Lust / using others in the mind— Jesus extends faithfulness to the heart and eyes (Matthew 5:27–28). This is the principle under the porn problem.
• Anything that degrades, coerces, or harmsyour spouse — because it violates the love and mutual self-giving that 1 Corinthians 7 and Ephesians 5 require. Coercion is never “your right.”

The Bible tells us that the marriage bed should be held in honour and it should be undefiled(Hebrews 13:4). So within marriage, the Bible’s posture is positive and free, while keeping faithfulness, love and the dignity of both people non-negotiable.

The grey middle (specific acts within marriage).Beyond the clear fences, Scripture doesn’t give a checklist of permitted/forbidden bedroom acts. Godly Christians have different opinions on this, formed on some basic principles. In many cases this is a conversation for you and your spouse in a way that honours each other.

And the one principle that should govern the rest is intimacy over intensity.

The marriage bed was never about aiming for maximum intensity; it was made for covenant closeness, which gives you a clean test for almost any question that comes up. Is this building intimacy and covenant between the two of us, and is my spouse genuinely glad of it?If yes, you’re free. If no, however permissible it might be in the abstract, let it go. Under that, a few more guiding principles that will help:

• Mutual consent and comfort— nothing one spouse finds degrading, painful or violating. Enthusiastic mutuality, not pressure.
• Faithfulness— nothing that brings a third party in, in body or mind (this is the real issue with porn and fantasy about others).
• Love and dignity— does it express care and “knowing,” or does it use the other person?
• Conscience and freedom— where Scripture is silent, couples have real freedom andthe right to a clear “no” without guilt; Romans 14’s conscience principle applies. No spouse should be pressured past their conscience, and no spouse should weaponise “the Bible doesn’t forbid it” to coerce.

Within marriage there’s a lot of freedom; the fences are faithfulness, mutual love, consent and dignity. Inside those fences, it’s between the two of you and God — and a clear conscience and a willing spouse matter more than any list.

Before marriage.

We believe that sex belongs inside the covenant of marriage (Part 10). But that leaves the question almost every dating and engaged couple has asked: so where’s the line?

Start with the “why,” not a list

The reason to wait isn’t that God is anti-pleasure or that sex is grubby (Part 1settled that). It’s that sex speaks a language. It says I am wholly yours, permanently, no one else.That sentence is only true once the covenant exists. To say it with your bodies before you’ve made it with your lives is to speak a promise you haven’t yet made, which is why it so often leaves people feeling used or confused, even when no one meant any harm.

Why a clear line actually serves you

Arousal is, by God’s design, an escalator — it’s built to carry a couple from a glance all the way to union without stopping, because inside marriage it doesn’t need to stop.

Before marriage it does.

And the further up the escalator you go, the harder and more arbitrary stopping becomes. So “how far is too far?” is the wrong question (it’s the question of someone hunting the maximum they can take); the better one is, “what helps us both keep the promise gladly, without a nightly battle?” Most couples who’ve done this well will tell you to decide together, in daylight rather than in the heat of the moment, where you’ll keep things — and decide it generously, with room to spare, not right at the edge.

A few tips

• Talk about it openly as a couple — the silence is what trips people up.
• Don’t engineer the situations that make it hardest (the empty house, the small hours, the bedroom).
• Stay accountable to someone older and wiser.
• If you’ve already gone further than you meant to, hear Parts 8 and 10together — there is full grace and a clean slate in Christ, and you can begin keeping the promise from today. A past is not a sentence.

A word to those already living together

Many couples reading this will be cohabiting, and none of it is said to shame you — it’s said because we’d be no friend to you if we stayed quiet about something we genuinely believe is good for you. If that’s you, you are welcome here exactly as you are, and we’d far rather talk it through honestly.

A word to singles.

Much of this framework is married-couple-facing, which can leave single people feeling either excluded or like they’re in a waiting room. Which is not what the Bible teaches.

Sex is not the pinnacle of human existence

Our culture treats sexual experience as essential to being a fully realised human. The Bible doesn’t. And Jesus Himself, the most fully human person who ever lived, was single and celibate. A full, flourishing, deeply intimate life is entirely possible without sex. That’s not a consolation prize; it’s a different and real truth.

Chastity is a positive practice, not just “not yet.”

In her book Real Sex: The Naked Truth About Chastity, Lauren Winner reframes chastity not as joyless white-knuckling but as a Christian discipline where you bring your body’s life under God’s good design, in a community, for love of God and others. It’s something you do, not merely something you don’t.

Singleness and desire are not problems to be ashamed of

Desire is part of the good design; the call is to steward it faithfully, which is hard and real and worth honouring rather than minimising. The reordered-desire principle in Part 9is for you as much as for anyone married. The goal was never a switched-off desire, but a rightly-aimed one. Single people need genuine intimacy too: deep friendship, community, belonging — and a church that only ever celebrates marriage fails them. That’s on us to fix.

Waiting well

For those headed toward marriage, the framing isn’t “endure deprivation now, flip a switch later” (we saw the damage that does in Part 2) but it is building, now, the trust, honesty and self-knowledge that great married sex is actually made of.

A word on same-sex attraction.

A resource like this will be read by people who experience same-sex attraction, or who love someone who does, and it would be remiss to stay silent. This is also the area where the surrounding culture and the historic church disagree most sharply, so our aim is to be clear and kind in equal measure.

We hold the traditional Christian understanding: that God’s design for sex is the covenant union of a husband and wife, and that this is the only context Scripture sanctions for sexual intimacy. That means we don’t believe same-sex sexual relationships are part of God’s design, which is, in fact, the same standard that asks a great deal of every unmarried person, whatever the direction of their desire.

However, we don’t want to wield this as a weapon. Same-sex attraction is not a sin to repent of having; it is not a sign someone is further from God than the rest of us; it is not “worse” than the heterosexual lust this whole framework has spent pages on. Someone who experiences it and follows Christ is not a problem to be fixed but a brother or sister to be loved, and often one carrying a costlier obedience than most of us are ever asked for.

The most credible voices here are believers who themselves experience same-sex attraction and have embraced this teaching — Sam Allberry (Is God Anti-Gay?), Wesley Hill (Washed and Waiting), Ed Shaw (The Plausibility Problem) — and they’re the ones to read, because they say all of this from the inside.

Where the church has to repent

Shaw’s point is that we’ve made this teaching implausibleby idolising marriage, romance and the nuclear family, so that “follow Christ in celibacy” sounds like “be lonely forever.” If we ask brothers and sisters to forgo romantic and sexual partnership, then we are obliged to be the deep, committed, lifelong family that makes such a life not just bearable but genuinely good (the church-as-family theme of Part 12). A church that preaches this ethic without becoming that family has no right to the words.

If this is you.You are welcome here, fully, not as a project, but as part of the family. Whatever you make of what we’ve written, we would count it an honour to walk with you, not preach condemnation at you.

Putting it together.

If you remember nothing else:

1. 01Sex is God’s good gift— for union, pleasure and (where given) children. He’s for it.
2. 02It’s lived before God— He’s the inventor, not the inspector. Inside marriage that makes sex a kind of worship; outside it, that’s why faithfulness matters even when no one would know. Who is already in the room?
3. 03Clear the rubble— obligation, shame and “men can’t help it” teaching do real harm; put them down.
4. 04Mutuality is the heart of it— both people matter equally; both pleasures count.
5. 05Knowing > technique— the goal is to be fully seen and fully accepted; mechanics serve that.
6. 06Difference is normal— arousal speed, responsive vs spontaneous desire, desire discrepancy. Understand it, don’t pathologise it.
7. 07Talk, out loud, kindly— to your spouse about the gift, and to one trusted person about the struggle. The highest-leverage skill there is.
8. 08Difficulties are common and usually fixable— pain, mismatch, dysfunction; name them, don’t endure in silence, get help when needed.
9. 09Sex changes through the seasons— pregnancy, small children, ageing, illness; the bed bends, and that’s normal, not failure. The honeymoon is the start, not the peak.
10. 10Wounds come first— where abuse or trauma is present, past or present, safety and gospel grace before any how-to.
11. 11Purity is reordered desire, not suppressed desire— the body is good and lust is a heart-posture, not skin; you win by wanting something more, not nothing. And there is a real person behind the screen.
12. 12Freedom inside faithful, loving, consenting bounds— the marriage bed is honoured; the test is intimacy over intensity; the fences are love, fidelity and dignity.
13. 13Sex isn’t ultimate— Christ is. Singles flourish; marriages flourish; both find their deepest intimacy in Him.
