This is one of those questions people search at 1 a.m. and never say out loud. The data has an unusually comforting answer: whatever is or isn’t happening in your marriage, it is far more common than anyone admits at dinner parties. Here are the real numbers, definitions included, because with this topic the definition is half the statistic.
The short answer: roughly 15 to 20% of American marriages are sexless under the standard research definition, sex ten or fewer times a year. About 7% of married adults had no sex at all in the past year, and 4% have gone five years or more, meaning as many as 1 in 7 marriages feature little to no sex. Rates rise steeply with age, and only 10–15% of these marriages end in divorce within five years.
As always: every number names who measured it and how, survey figures are labeled with their populations, and the sources are at the bottom.

What percentage of American marriages are sexless?
“Sexless” sounds binary. The data is a ladder, and where you draw the line changes the answer:
1. 15 to 20% of American marriages are sexless under the standard research definition.
Ten or fewer times a year is the threshold clinicians and sociologists converged on, roughly less than once a month. By that line, somewhere between one in seven and one in five American marriages qualifies. If that number surprises you, that is the point of this page: this is common and almost entirely undiscussed.
2. 7% of married US adults had no sex in the past year; 4% have gone five years or more.
The strict zero-activity cut, from nationally representative surveys. Note the gap between 7% and 4%: for most fully sexless marriages, the drought is measured in years, not months.
3. Counting little-to-no sex together, it’s about 1 in 7 US marriages (14–15%).
Lehmiller’s synthesis of the survey data. One in seven means statistically, several couples on your street, several in your office, several at every wedding you attend. Nobody mentions it, which is why the search phrasing for this topic is always anonymous and always at night.
4. The “ten times a year” line is a research convention, not a diagnosis.
It dates back to sociologist Denise Donnelly’s 1990s work on sexually inactive marriages. There is nothing magic about the number ten: a couple at twelve times a year is not officially fine, and a couple at eight is not officially broken. Researchers needed a line; the line stuck. What matters clinically is whether both partners are content, more on that below.
Sexless marriage statistics by age
Every long-tail version of this search, after 50, after 60, after 70, has the same honest answer: frequency declines with age in every dataset we have, and here is the cleanest one.
5. Among older US adults, sexual inactivity reaches roughly 40% or more past the late 50s.
The landmark aging study found 73% of 57–64-year-olds sexually active in the past year, falling to 53% at 65–74 and 26% at 75–85. So yes: a sexless marriage after 60 or 70 is statistically closer to normal than to exceptional. Health, medications, and a partner’s health explain much of it, not lost love.
6. The twist: this is no longer just an age story. Partnered frequency has declined across every cohort.
American adults, including the young and the married, report less sex than the same groups did in the 1990s, a decline of roughly nine times per year on average. Screens, stress, and later marriage all get blamed; the honest answer is that researchers are still arguing. The broader don’t-date-anymore data gets its own page in this series.
Sexless marriage around the world
One international comparison dominates this topic, and it comes with a definition warning.
7. Japan: 47 to 68% of married couples report being sexless, by far the highest widely cited figure.
Crucial caveat: Japan’s surveys count couples with no sex in the past month, a much looser line than America’s ten-times-a-year definition. Japan’s numbers are genuinely high and rising, but comparing 68% to America’s 15–20% without noting the different rulers is exactly the kind of statistical malpractice this series exists to avoid.
8. Comparable data for most other countries, including the UK, is thin and inconsistently defined.
UK surveys suggest broadly similar territory to the US, with fewer-than-monthly sex common in long marriages, but no national survey uses the ten-a-year line, so I won’t manufacture a precise percentage. Where good data doesn’t exist, this page says so.
Why sex disappears, and what it does to people
The best study on this recruited people in sexless marriages who wanted sex and asked them directly: what happened, and how does it feel?
9. The most cited cause is a partner’s loss of desire, followed by relationship problems, sexual dysfunction, illness, appearance concerns, and infidelity.
For most couples the slide was gradual, one factor compounding another; for some it stopped abruptly, and some never had much of a sex life to begin with. There is no single road into a sexless marriage, which is partly why there is no single road out.
10. Reactions were almost universally negative: frustration, depression, feelings of rejection, and low self-esteem.
Participants described intrusive preoccupation, damaged confidence, and effects bleeding into work. Worth stating because the internet is full of “sexless and thriving” content: for people who still want intimacy and aren’t getting it, the research says it genuinely hurts.
11. The lower-desire partner is sometimes the husband and sometimes the wife.
Every gendered stereotype about this topic fails the data. Search trends ask about the effect on wives; the studies find men and women on both sides of the desire gap, and both sexes reporting the same distress when they’re the one still wanting.
12. Sexless marriage correlates with lower reported happiness, but not automatically with a bad marriage.
Sexlessness is associated with lower happiness on average, yet plenty of surveyed couples report satisfied, affectionate, low-or-no-sex marriages, usually when both partners’ desire declined together. The research consensus in one line: a sexless marriage is a problem when it’s a problem for one of the people in it.
Do sexless marriages end, and how do people cope?
The most surprising numbers on this page: how rarely these marriages break, and what people do instead of leaving.
13. Only 10 to 15% of sexless marriages end in divorce within five years.
Sexlessness raises divorce risk, the correlation is real, but the overwhelming majority of these marriages continue. Whatever holds a marriage together, the data says it is usually more than this one thing.
14. 47% stay because, apart from the sex, they consider their partner ideal.
The most human statistic in this dataset. Nearly half of the people surveyed weren’t trapped by finances or fear; they were staying for a person they loved. Others cited children, shared investments, or faith. Only a minority stayed out of fear or a sense of having no options.
15. A 2008 study found 13–14% coping through “cybersex or phone sex”. In 2026, that category has a new name.
That coping bar aged into an industry. Today nearly 1 in 5 US adults have chatted with a romantic AI, and about 15% of partnered young adults use one regularly, numbers I unpack in my AI companion statistics. The intimacy gap didn’t change; the technology filling it did.
When intimacy goes quiet, people find somewhere to put the feelings.
Some talk to a therapist, which the research genuinely supports. Some talk to no one. And a measurable, growing number now talk to an AI companion, which happens to be the market I research and test firsthand. If you’re curious what that side of the data looks like, the numbers are in my AI girlfriend statistics, and the apps themselves are compared on my homepage.

So, what percentage of American marriages are sexless? Around 15 to 20% by the standard definition, 7% with no sex in the past year, rising to a statistical majority in the oldest cohorts, and ending in divorce far less often than the distress would predict.
My read as a data researcher: the headline number isn’t the 15–20%. It’s the 47% who stay because everything except the sex still works. Sexless does not mean loveless, and the data describes one of the most common, most survivable, and least discussed situations in American marriage. The silence around it is the only part that isn’t normal.
FAQs
What percentage of American marriages are sexless?
About 15 to 20% under the standard research definition of sex ten or fewer times a year. Using stricter cuts, roughly 7% of married US adults had no sex in the past year and 4% have gone five or more years. Combined with near-sexless marriages, about 1 in 7 US marriages feature little to no sex.
What counts as a sexless marriage?
Researchers define it as sex ten or fewer times per year, roughly less than monthly. The threshold is a research convention from 1990s sociology, not a clinical diagnosis: therapists generally treat a sexless marriage as a problem when the frequency distresses one or both partners, not when it crosses a number.
What percentage of sexless marriages end in divorce?
Only about 10 to 15% end in divorce within five years. Sexlessness is associated with elevated divorce risk and lower average happiness, but most sexless marriages persist, most commonly because partners value the rest of the relationship: 47% of people in one study stayed because they otherwise considered their partner ideal.
Is a sexless marriage normal after 50, 60, or 70?
Statistically, it becomes increasingly common: 73% of adults 57–64 were sexually active in the past year, dropping to 53% at 65–74 and 26% at 75–85. Past 70, a sexless marriage is closer to the norm than the exception, with health and a partner’s health, not lost affection, driving most of the decline.
When should you walk away from a sexless marriage?
The data can’t answer that for you, but it can frame it: most people stay, distress is highest when only one partner wants change, and couples who address it openly or with professional help report better outcomes than those who go silent. If the situation is causing you real distress, the evidence-backed move isn’t a statistic, it’s a certified couples or sex therapist.
