A sexless marriage is one of the most common situations couples find themselves in, and one of the loneliest, partly because so few people talk about it openly. Estimates from the National Health and Social Life Survey suggest that roughly 15-20% of married couples could meet the clinical definition at any given time. Most of them are not in obviously failing relationships. Most of them love each other. Most of them have no idea that the situation they're in is, in fact, common.

This article is the honest version of this topic. We'll cover what counts as a sexless marriage (the definition is more useful than people think), what actually causes it ranked roughly by frequency, what the impact really looks like over years, and the question almost no article on this topic is willing to answer directly: how do you decide whether to stay or leave. There's no single right answer, but there is a framework, and being clear about it is more useful than the moralizing or vague reassurances most articles offer.

What "sexless marriage" actually means

The clinical working definition, used by most sex therapists and researchers including the Gottman team, is a relationship in which the couple has sex fewer than ten times per year. Some clinicians use "less than once a month" as a softer threshold.

The number itself isn't really the point. What matters is the gap between what's happening and what one or both partners want to be happening. A couple having sex four times a year who are both content with that frequency is not in a problematic situation. A couple having sex twice a month where one partner is quietly suffering about the lack and the other doesn't know it is, regardless of where they fall on the technical definition.

The more useful framing is to ask three questions:

  1. Is this what at least one of us wants? A relationship can have very low frequency and be fine if both partners are content. The problem is when one partner isn't.
  2. Is this connected to other erosions? A couple with low sex frequency who are still emotionally close, affectionate, and turning toward each other is in a different situation than a couple where the lack of sex is the most visible symptom of a broader disconnection.
  3. Has this become permanent? Many couples go through six-month or year-long stretches of low or no sex, often around big life transitions (a baby, an illness, a job loss). These are different from the patterns that have stabilized into the relationship's ongoing reality.

If the answer is "no, yes, yes" to those three, the situation is worth taking seriously even if the frequency wouldn't technically count as sexless.

Why it actually happens, in rough order of frequency

Most articles on this topic list five to ten causes as if they're equally common. They're not. The honest distribution looks more like this.

1. The slow drift, with no specific cause

This is by far the most common pattern. There's no event, no betrayal, no obvious problem. Two people who used to have a vibrant sex life simply stopped, gradually, over months or years. Each individual postponement made sense at the time (we're tired, the kids are sick, work has been awful). The cumulative effect was a quiet calcification.

Couples in this category often have no idea how it happened, which is part of why it's so hard to fix. There's no clear thing to address. The accumulation of a thousand small choices doesn't reverse itself by addressing any one of them.

2. Resentment that has stopped being talked about

Specific to long-term couples. One partner is angry about something (the unequal share of housework, a slight that was never addressed, money tension, a relationship to a parent or in-law) and that anger has gone underground. They don't think of themselves as withholding sex. They just notice they're not interested. The interest is, in fact, blocked by the unspoken anger, but neither partner has connected the dots.

This is often the most fixable cause when it's named, because the underlying issue, once surfaced, can be addressed. Couples who do this work often report that the sex returns as the resentment is metabolized.

3. Mismatched libidos that have never been worked through

Two partners with genuinely different baseline levels of sexual interest who have never developed a way to talk about it that doesn't make either of them feel rejected or pressured. Over years, the higher-libido partner stops asking because asking has become painful. The lower-libido partner stops initiating because they don't really want to. The result is a frequency that's often closer to zero than either would actually choose.

This is technically called "desire discrepancy" and it's one of the most common reasons couples seek sex therapy. It's also one of the most workable patterns when addressed early and one of the hardest when it's been calcifying for a decade.

4. Postpartum, perimenopause, and other hormonal shifts

The physiological causes are real and underdiscussed. After childbirth, especially the first one, both partners often experience significant changes in libido that can take 12-24 months to stabilize. Perimenopause and menopause produce hormonal changes that meaningfully affect interest in sex for most women. Low testosterone in men has similar effects. These are medical realities, not relationship problems, but they're often experienced and interpreted as relationship problems, which makes them worse.

5. Medication side effects

SSRIs (the most common antidepressants) reliably suppress libido in a significant percentage of users. So do many forms of hormonal birth control. Several common blood pressure medications. Most prescribers are not very good at proactively warning patients about this, so the libido drop often appears mysterious until someone connects it to the medication start date.

6. Untreated mental health issues

Depression suppresses sexual desire. Chronic anxiety does too. Untreated trauma, especially sexual trauma, frequently shows up as gradually disappearing interest in sex. None of these are relationship failures but they often look like relationship failures to the partners experiencing them.

7. The everyday infrastructure has eroded

Low sex is often downstream of the smaller infrastructure of intimacy collapsing. The couple has stopped touching casually during the day. Stopped lingering when they kiss goodbye. Stopped going to bed at the same time. Stopped having unstructured time together. The bedroom doesn't recover when everything around it has quietly emptied out. (Our companion article How to Fix a Dead Bedroom covers the practical playbook for rebuilding this layer.)

8. The deeper relationship has changed and nobody has named it

The least common but most serious cause. One or both partners has, over time, become genuinely less interested in this relationship as a whole, and the absence of sex is the most visible symptom of that broader shift. This is different from the slow drift in (1). It feels different from the inside. The partners can usually tell, if they're honest with themselves, which one they're in.

What it actually does to people, over years

Most articles soften this part. The honest version is:

A sexless marriage that one partner is unhappy about is, over a long enough timeline, one of the more painful situations in adult life. Not because of the absence of sex specifically, but because of what the absence comes to mean. The unhappy partner experiences a steady erosion of self-worth and desirability. They start to feel invisible in a specific way. The relationship becomes a place where a fundamental need is going unmet, in proximity to the person they're supposed to be most intimate with, which is a particular kind of loneliness that doesn't have a clean name.

The partner with lower interest also suffers, often in ways that are less recognized. They feel constantly behind on something they didn't know they were supposed to be ahead on. They feel guilty when they say no, and resentful when they feel they have to say yes. They start to dread closeness in any form because closeness might be misread as initiation.

Both partners often experience a slow loss of trust, not in the partner's fidelity necessarily, but in the relationship's capacity to meet either of them where they actually are. That loss of trust does most of the long-term damage. The sex itself, in the end, often matters less than what the absence of it has come to symbolize.

What actually works (when something works)

The interventions that have the best track record, drawn from sex therapy research and clinical practice:

Naming the situation, together, without either partner being the problem. Most couples in long-standing sexless marriages have not had a single direct, calm conversation about what's actually happening. The conversation that works isn't "why don't you want me." It's something closer to: I've noticed we've drifted into a pattern that I don't think either of us would have chosen on purpose. I want to talk about what we actually want, not what we're each assuming about the other.

Ruling out the medical and hormonal layer first. Before doing relationship work, both partners should have a frank conversation with their doctors about libido. Postpartum, perimenopause, low testosterone, medication side effects, depression, untreated sleep apnea: addressing what can be addressed at the body level removes a major confounding variable from the relationship conversation.

Rebuilding non-sexual touch first, sex later. This counterintuitive approach (often called a "sex embargo" in the Gottman framework) involves both partners agreeing that sex is off the table for a defined period while deliberately rebuilding hand-holding, hugging, lingering touch, sleeping touching. The pressure removal often paradoxically allows interest to return. This is the central practical move in our Dead Bedroom playbook.

Surfacing the underlying resentment. If the cause is buried anger, the fix is the conversation about the anger, not about the sex. The sex is downstream. Couples who try to fix the sex without addressing what's underneath usually rebound to the same place within months.

Sex therapy specifically, not just couples therapy. General couples therapists vary widely in how comfortable they are with this topic. Sex therapists certified by the American Association of Sexuality Educators, Counselors and Therapists (AASECT) have specific training and tend to be much more useful here.

Patience with how slow this is. Sexless patterns that have been building for years rarely reverse in weeks. Twelve to eighteen months of consistent work is not unusual for a real shift. Couples who expect quick reversals usually give up at the six-week mark, just as the harder work was starting.

The honest question of whether to stay

This is the question almost every other article on this topic dances around. Let's actually try to answer it.

There's no universal right answer, but there is a framework that's more useful than the moralizing most articles offer. The question of whether to stay in a sexless marriage essentially comes down to four sub-questions, which most people benefit from answering separately rather than as one tangled judgment.

Question 1: Is the other partner willing to engage with this?

This is the threshold question. A partner who is willing to acknowledge the situation, consider that it's a problem, talk about it openly, and engage in the work of changing it is a partner you can build something with, even if the work is hard and slow. A partner who refuses to acknowledge it, dismisses it, blames you for raising it, or has been promising change for years without delivering any is signaling something different.

If the answer is no, you're not really facing a question about the marriage. You're facing a question about whether you can accept the marriage as it currently is, knowing that it's unlikely to change.

Question 2: How are you doing as a person in this?

Some people in sexless marriages, especially after working on it, can find a peace with the situation. Some genuinely find that it doesn't bother them after a while. Some discover that other parts of the relationship matter more to them than they realized. These outcomes are real and not failures.

Other people in sexless marriages experience a slow erosion of their sense of themselves. They feel less alive, less desirable, less sure of who they are. They notice they're more attracted to friends, coworkers, strangers, in ways they didn't used to be. They feel themselves performing a version of contentment they don't actually feel.

There is no judgment in either of these. Both are real responses to a hard situation. The question is which one is true for you, honestly.

Question 3: What else is in this relationship?

A sexless marriage that is otherwise rich, deeply emotionally connected, kind, mutually supportive, and structurally functional is a different situation than a sexless marriage that is also low on emotional intimacy, kindness, partnership, or care. The first is something many couples can build a workable life around if they choose to. The second is usually a marriage that has already substantially ended, and the absence of sex is one symptom among many.

Question 4: What does staying actually cost you, and what does leaving actually cost you?

The framing most articles offer is "stay if it's fixable, leave if it's not." That framing isn't quite right. The more honest framing is that both staying and leaving have costs, and you have to be honest about both.

The costs of staying in a sexless marriage that doesn't change might include: years or decades of low-grade loneliness, the slow erosion of a part of yourself, the cumulative effect on your physical and emotional health.

The costs of leaving might include: the ending of a relationship that has many other goods in it, financial and structural disruption, impact on children if there are any, the absence of guarantee that the next relationship will be better, the work and grief of dismantling a shared life.

Neither column is automatically heavier than the other. It depends on the specifics of your life, your relationship, your circumstances, and what you can live with. The question is not which choice is correct in the abstract. The question is which set of costs you'd rather carry.

A quieter reframe

The most useful thing to know about sexless marriage is that it isn't, by itself, a verdict on a relationship. It's a situation. Some situations are workable with attention, honesty, and time. Some aren't. Most articles either oversimplify (it's fixable, you just have to communicate) or pathologize (it's a sign your marriage is dying), and neither is universally true.

What's universally true is that the situation rarely improves by being avoided. The couples who do best, whether they end up staying together with a richer sex life, staying together with a workable peace around the situation, or eventually choosing to part, share one thing in common: they stopped pretending the situation wasn't real, named it openly, and made a conscious choice rather than letting time make the choice for them.

That choice, whatever it is, is yours to make. The harder work is being willing to actually face it.

FAQ

What is the technical definition of a sexless marriage?

Most sex therapists and researchers use the threshold of having sex fewer than ten times per year. Some use "less than once a month" as a softer working definition. Both are useful working numbers, but the more important question is whether the level of sexual frequency is what at least one partner actually wants.

How common is a sexless marriage?

Estimates from the National Health and Social Life Survey suggest that roughly 15-20% of married couples could meet the clinical definition at any given time, with prevalence increasing significantly with age. The actual number is likely higher, because couples often underreport.

Can a sexless marriage be saved?

Often, yes, especially when both partners are willing to engage with the work, when the underlying causes (medical, emotional, relational) are honestly addressed, and when there's a realistic timeline (often 12-18 months) for the change. The harder cases are ones where one partner refuses to acknowledge the situation, where chronic underlying resentment has gone unaddressed for years, or where the broader emotional connection has substantially eroded.

Is it normal to want to leave a sexless marriage?

Yes. Wanting to leave a relationship in which a fundamental need is going unmet is not a moral failing. The question is what you decide to do with that wanting, after honest reflection on whether the situation might change, what else is in the relationship, and what staying or leaving would actually cost.

What's the difference between a sexless marriage and a low-sex marriage?

A "low sex" marriage where both partners are content with the level of sex they're having isn't a problem, regardless of frequency. A sexless or low-sex marriage where one or both partners is suffering about the absence is the situation worth addressing. The distress matters more than the frequency.

Should I stay if my partner refuses to address the issue?

This is the question only you can answer, and the most honest framework is: a partner who will not acknowledge or work on the situation is unlikely to change without that engagement. Staying in that case is choosing to accept the marriage as it currently is, possibly indefinitely. Whether you can do that, and at what cost to yourself, is the question worth being honest about.

Are sexless marriages more common in long marriages or new ones?

The pattern is more common in longer marriages, partly because some causes (the slow drift, accumulated resentment, hormonal changes with age) take time to develop. New marriages with very low sex are a different situation and often signal something specific (mismatched libidos that were always there, untreated trauma, ambivalence about the marriage itself) that's worth addressing directly.
