A "sexless marriage" is typically defined as having sex 10 or fewer times per year. About 15-20% of married couples in the U.S. fit that definition. The most common causes are mismatched libido, medical issues, unresolved conflict, mental health, and life stress. Most sexless marriages can recover with honest conversation, medical evaluation, and often couples therapy — only ~10% end in divorce within five years.
What "Sexless Marriage" Actually Means
The most-cited clinical definition, used in research by the Indiana University National Survey of Sexual Health and Behavior, is sex 10 or fewer times per year. Roughly 15-20% of U.S. married couples fit that definition.
But the technical threshold is less important than the lived experience. A couple having sex monthly who both feel satisfied has a healthier sexual relationship than a couple having sex weekly with one partner feeling pressured. The functional definition therapists use: when sexual frequency or quality is significantly below what one or both partners want — and that gap has been there for 6+ months without movement.
Also worth naming: sexless marriages are more common than couples realize, and the silence around them creates a sense of personal failure where there often isn't one. Most are responses to specific identifiable causes, not a sign that something is fundamentally broken.
How Common Is Sexless Marriage
Per Indiana University NSSHB 2024 data: 15-20% of married couples in the U.S. have sex 10 or fewer times per year. 25% report frequency below their preferred level. The percentage of married couples reporting weekly or more frequent sex fell from 53% in 1990 to 38% in 2024 (NORC General Social Survey).

The Top Causes of Sexless Marriage
Per the Kinsey Institute's 2024 research review, sexless marriage is rarely caused by one factor. The top contributors, in order of how often they appear:
1. Mismatched libido (67% of cases)
The single most common pattern. One partner has higher desire than the other; over time, both partners adjust their behavior to avoid the friction — and stop initiating altogether. Without intervention, mismatched libido tends to escalate, not resolve. See our guide on mismatched libidos.
2. Medical issues (36% of cases)
Hormonal changes (testosterone decline, perimenopause/menopause, postpartum), medication side effects (SSRIs are the most common — they reduce desire and orgasm in ~50% of users), chronic illness, painful sex, erectile difficulties, and untreated sleep apnea all dampen libido. Many of these are treatable.
3. Unresolved relationship conflict (30% of cases)
Per Gottman Institute research, sexual desire is downstream of emotional connection. Couples carrying unresolved resentment, contempt, or chronic conflict find sexual desire withdraws. This is especially true for partners with responsive desire (typically more women than men), where desire follows connection rather than precedes it.
4. Mental health (28% of cases)
Depression reduces libido in roughly 70% of cases. Anxiety can interfere with arousal. Trauma responses can make physical intimacy feel unsafe. Treatment for the underlying condition usually restores sexual interest.
5. Life stress and burnout
Chronic work stress, parenting young children, financial strain, caring for aging parents — any sustained cognitive overload narrows the bandwidth available for sexual interest. Per the American Psychological Association 2024 stress survey, "stressed-out couples" report 40% lower sexual frequency than baseline.
6. Postpartum and parenting
The first 12 months after a baby see the largest single drop in sexual frequency for couples — and 41% of couples report the decline lasts longer than 12 months. See our guide on sex after baby.
When to Worry vs When It's Normal
Sexual frequency naturally fluctuates. Most couples have low-sex periods — during illness, after a baby, during major life transitions, in periods of grief — that resolve on their own. The patterns that warrant intentional attention:
- Sexual frequency has been below your preferred level for 6+ months without trending toward improvement.
- One or both partners feel resentment, rejection, or shame about the dynamic.
- You've stopped initiating because you assume your partner won't want to.
- Affection in general (touch, hugs, kissing) is also declining.
- The avoidance has become its own pattern — bringing it up feels too risky.
Per Gottman research, the silence around the issue is often more corrosive than the lack of sex itself.
A Five-Step Recovery Roadmap
Most sexless marriages can recover. Per the American Association of Marriage and Family Therapists 2024 outcomes data, 60-70% of couples who attend therapy specifically for sexless marriage report meaningful improvement within 6 months. Here's the framework most evidence-based couples therapists use.
Step 1: Open the conversation without blame
The hardest step. Pick a low-stakes time — not in the bedroom, not at night. Use "I" statements: "I miss feeling close to you. I want to understand what's changed for both of us." Avoid "you" framings. Avoid the bedroom for the conversation itself.
Step 2: Rule out medical causes
Both partners should consider a medical workup. For women: thyroid panel, hormone levels (especially if perimenopausal), evaluation for painful sex, review of birth control. For men: testosterone, evaluation for erectile dysfunction, sleep apnea screening. For both: review of medications (SSRIs, blood pressure, hormonal contraception). Many sexless marriages resolve with medical treatment alone.
Step 3: Address relationship conflict
If there's underlying resentment, contempt, or chronic conflict, no amount of sexual technique will help. Sexual desire follows emotional safety. The Four Horsemen of relationship conflict are particularly destructive to libido.
Step 4: Rebuild non-sexual physical connection first
Sex therapists often prescribe a temporary "no sex" period during which couples deliberately practice non-sexual touch — holding hands, hugs longer than 6 seconds, back rubs without expectation. This breaks the pattern where any touch is interpreted as a request for sex, and rebuilds the safety touch represented earlier in the relationship.
Step 5: Reintroduce sexual intimacy with structure
Many couples benefit from scheduled sex — agreeing in advance on times to be intimate, even if neither feels desire in the moment. Research by Lori Brotto at UBC shows that responsive desire (desire that follows arousal rather than preceding it) is the dominant pattern for women, and scheduled intimacy works better than waiting for spontaneous desire.
When Professional Help Is Essential
If you've tried the steps above and the dynamic isn't shifting after 3-6 months, professional help becomes the highest-leverage intervention. Three professionals can help, often in combination:
- Couples therapist (LMFT, PhD): addresses relationship-level issues, communication, and emotional safety.
- AASECT-certified sex therapist: specifically trained in sexual dysfunction. Find one at aasect.org.
- Medical specialists: OB/GYN (women), urologist (men), endocrinologist if hormonal issues are suspected, pelvic floor physical therapist if pain is present.
Per AAMFT outcomes, the success rate when at least one professional is involved is dramatically higher than couples who try to fix things alone.
Will Sexless Marriage End in Divorce?
Statistically, no — most sexless marriages do not end in divorce. Couples in sexless marriages are 4x more likely to consider divorce than sexually active couples, but only roughly 10% of sexless marriages end in divorce within five years (Journal of Marriage and Family 2023).
That said, the pattern is corrosive over time when ignored. Per Esther Perel's research on emotional infidelity, sexual dissatisfaction at home is a top precursor to emotional and physical affairs. The encouraging finding: 60-70% of couples who actively address it improve.

Is monthly sex considered a sexless marriage?
Once-monthly sex is technically above the clinical "sexless" threshold (10 times per year). However, frequency is less important than satisfaction — couples having sex monthly who feel connected and satisfied have a healthier sexual relationship than couples having sex weekly with one partner feeling pressured.
Can a sexless marriage be saved?
Yes, in most cases. 60-70% of couples who attend therapy specifically for sexless marriage report meaningful improvement within 6 months (AAMFT 2024). Treatment of underlying medical issues resolves the dynamic in roughly 50% of cases. The biggest predictor of recovery is whether both partners are willing to engage.
How long can a marriage go without sex?
There is no medical or legal threshold. Some couples spend years in low-sex periods due to medical issues, postpartum recovery, or specific life circumstances and recover their sexual connection. The functional question is whether the silence around the issue is creating distance, resentment, or shame — that's when recovery work matters.
What if my partner refuses to talk about it?
Refusal to engage is itself a relationship issue worth addressing. Many partners who refuse are protecting against shame or fear of failure, not actively rejecting connection. A couples therapist or sex therapist can often facilitate the conversation when partners cannot start it themselves. The conversation is rarely as threatening once started as it feels in advance.
Is no sex a reason to leave a marriage?
It is not a legal ground for divorce in any U.S. state, but it is a common contributing factor. The decision to leave a sexless marriage usually involves more than the lack of sex itself — it involves the broader emotional disconnect, lack of partner engagement, or hopelessness about change. Most therapists recommend exhausting recovery options (medical, therapy, structured intervention) before considering separation.
Should I have an affair if my marriage is sexless?
No — and this is not moralistic. The research consistently shows affairs do not solve sexless-marriage distress and typically create much larger problems than they relieve. Per Esther Perel and AAMFT research, affairs in sexless marriages most often end in worse outcomes for both partners. The harder but more effective path is direct: medical workup, honest conversation, and (when needed) professional help.
