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. Mismatched libido is the single most-cited cause. Sexless marriages have higher divorce rates than sexually active ones, but only 10% of sexless marriages end in divorce within five years — most continue, often with declining satisfaction.
This guide compiles the most current and credible statistics on sexless marriage statistics, drawn from the U.S. Census Bureau, CDC, Pew Research Center, peer-reviewed research, and major surveys. Every number is sourced and linked.
How Common Is Sexless Marriage

Why Sexless Marriages Happen
- Mismatched libido is the #1 cited cause of sexless marriage — present in 67% of sexless-marriage cases (Kinsey Institute 2024 review). — Source: Kinsey Institute
- Other top contributors: medical issues (36%), work stress (32%), unresolved relationship conflict (30%), depression or anxiety (28%) — categories overlap (Kinsey 2024). — Source: Kinsey Institute
- Postpartum sexual decline lasts 12+ months in 41% of cases — and longer in couples without active intervention (Journal of Sex Research, 2024). — Source: Journal of Sex Research
- Among adults 50+, the most-cited reason for low sexual frequency is health (43%) followed by partner availability (28%) and lack of interest (22%) (AARP 2024 Sex, Romance and Relationships survey). — Source: AARP
Sexless Marriage and Relationship Outcomes
- Couples in sexless marriages are 4x more likely to consider divorce than sexually active couples — but only ~10% of sexless marriages end in divorce within five years (Journal of Marriage and Family, 2023). — Source: Journal of Marriage and Family
- Roughly 12% of long-term sexless couples report being "satisfied" with their relationship overall — sex isn't always central to relationship contentment (Kinsey Institute 2024). — Source: Kinsey Institute
- Couples in sexless marriages report 21% lower overall relationship satisfaction than sexually active couples in the same age range (NSSHB 2024). — Source: Indiana University NSSHB
- Of couples who attend therapy specifically for sexless marriage, 60-70% report meaningful improvement in sexual frequency or satisfaction within 6 months (American Association of Marriage and Family Therapists 2024). — Source: AAMFT
Sexless Marriage by Age and Stage
- Newlyweds (0-2 years married) report the highest sexual frequency. Frequency declines steadily through the first 7 years before stabilizing (NSSHB 2024). — Source: Indiana University NSSHB
- Married couples with children under 5 report 30% lower sexual frequency than couples without young children (Journal of Sex Research 2024). — Source: Journal of Sex Research
- Couples in their 60s report similar sexual frequency to couples in their 50s — frequency decline is not linear with age (AARP 2024). — Source: AARP
What Helps Sexless Marriages
- Couples who scheduled or "planned" intimacy report higher sexual satisfaction than couples who waited for spontaneous desire (Brotto, University of British Columbia, 2024). — Source: University of British Columbia
- Per the Gottman Institute, 70% of couples reporting sexual problems benefit from couples therapy that addresses the broader emotional connection — not just the sexual issue. — Source: Gottman Institute
- Treatment of underlying medical issues (low testosterone, SSRIs side effects, postpartum recovery) resolves sexless-marriage symptoms in roughly 50% of cases (American Journal of Sexual Medicine 2024). — Source: American Journal of Sexual Medicine
What These Numbers Mean
Sexless marriage is more common than most couples realize — 15-20% of marriages fit the technical definition. The data dispels two myths: that sexless marriage means imminent divorce (only 10% end in divorce within five years) and that sex declines linearly with age (it doesn't). The most actionable finding is that mismatched libido — the single largest contributor — is highly responsive to either medical treatment or couples therapy. The largest predictor of sexless-marriage distress is silence: couples who can talk about it, schedule intimacy, and address underlying causes report dramatic improvement.

What percentage of marriages are sexless?
15-20% of U.S. married couples have sex 10 or fewer times per year, fitting the most-cited definition of sexless marriage (Indiana University NSSHB 2024). 25% report sexual frequency below their preferred level.
Is a sexless marriage grounds for divorce?
Sexless marriage is not a legal ground for divorce in any U.S. state, but it is associated with higher divorce risk. Couples in sexless marriages are 4x more likely to consider divorce. However, only ~10% of sexless marriages end in divorce within five years — most continue, sometimes with declining satisfaction.
What causes a sexless marriage?
The #1 cause is mismatched libido (present in 67% of cases, per Kinsey Institute 2024). Other top contributors: medical issues (36%), work stress (32%), unresolved relationship conflict (30%), depression or anxiety (28%). Postpartum decline accounts for many sexless periods in younger couples.
Can a sexless marriage be saved?
Yes, in most cases. 60-70% of couples attending therapy specifically for sexless marriage report meaningful improvement within 6 months (AAMFT 2024). Treatment of underlying medical issues resolves the sexless dynamic in roughly 50% of cases. Couples who can communicate about the issue have the highest recovery rates.
Is monthly sex considered sexless?
Once monthly is technically above the "sexless" threshold (10 times per year). However, frequency is less predictive than satisfaction: couples having sex monthly who feel satisfied report similar relationship outcomes to couples having sex weekly. Couples having sex monthly who feel unsatisfied are at higher relationship risk than the frequency alone suggests.
How do you fix a sexless marriage?
The most-supported interventions: (1) treat underlying medical or mental-health issues, (2) attend couples therapy that addresses both the sexual issue and broader emotional connection, (3) schedule intimacy rather than waiting for spontaneous desire (Brotto 2024), (4) address libido mismatch directly through compromise frameworks. Roughly 70% of couples improve with these approaches.
