How Often Does the Average Man Have Sex: By Age

Men in their twenties have sex roughly 80 times a year on average, while men in their sixties average closer to 20 times a year, according to nationally representative U.S. survey data spanning decades.¹ That four-to-one ratio captures the broad shape of the age curve, but the story underneath those averages is more interesting than the numbers alone suggest. Frequency varies widely within any age group, recent generations are trending differently than their predecessors, and the reasons behind the decline involve far more than biology.

The Twenties and Early Thirties

This is typically when men report the highest sexual frequency. The roughly 80-times-per-year average for men in their twenties works out to about once every four to five days, though that figure blends together men who are having sex several times a week with those who are not having sex at all. A national probability survey found that vaginal intercourse in the previous 90 days was most common among men in their late twenties and thirties compared to all other age groups.²

The picture has shifted in recent years, though. Among men aged 18 to 24, the share reporting weekly or more sexual activity dropped from about 52% to 37% between 2000 and 2018. Over the same period, sexual inactivity in that age group climbed from roughly 19% to 31%.³ For men aged 25 to 34, sexual inactivity doubled from 7% to 14%, and weekly-or-more activity fell from about 65% to 50% during the same window.³ So while young men still report the highest average frequency of any age group, that peak has gotten noticeably lower over the past two decades.

The Mid-Thirties Through the Forties

Men in the 35-to-44 range historically reported having sex a bit less often than those in their late twenties, but this group still averaged well above once a week for much of the survey period. By the late 2010s, weekly-or-more activity among these men had slipped from about 61% to 50%.³ Unlike the younger age groups, though, the share of men in their late thirties and forties who were sexually inactive stayed largely flat. The shift here was more of a gradual easing from frequent sex to moderate sex, with more men moving into the one-to-three-times-per-month range, rather than a dramatic jump in men having no sex at all.

This is also the decade when many men are deep into long-term partnerships and parenting, and the demands of those roles tend to redistribute how couples spend their time and energy. The general trajectory through the forties, for most partnered men, is a slow tapering rather than a sudden cliff.

The Fifties, Sixties, and Beyond

Frequency continues to decline through middle age and into later life, but the decline does not mean sex disappears. A large global study of men and women over 40 found that sexual desire and activity remain widespread among middle-aged and older adults and persist into old age.⁴ The U.S. national probability survey found that about half of men in their sixties and seventies reported vaginal intercourse in the preceding 90 days.² That is a meaningful drop from the near-universal rates men report in their twenties and thirties, but it is far from negligible.

By the sixties, the annual average has dropped to around 20 times per year.¹ Some men in that bracket are having sex weekly; others have stopped entirely. Poor physical health at older ages is a significant driver of that decline, and research suggests the connection between overall well-being and sexual frequency also changes over time, meaning that health matters to sexual frequency in different ways as men age.⁵ Among men aged 75 to 95, higher testosterone levels were associated with being sexually active, though many men in that range remain sexually engaged regardless of hormone measurements.⁶

Why Frequency Drops With Age

The decline in sexual frequency across a man’s lifespan is not caused by any single thing. Several forces pile up over time, and they interact with each other in ways that make it hard to isolate one culprit.

Testosterone does play a role. In older men with sexual dysfunction, researchers have found a clear link between lower testosterone and more severe erectile problems, as well as a positive connection between testosterone and how often men have intercourse.⁷ But testosterone drops gradually, usually about 1-2% per year starting in a man’s thirties, and many men maintain perfectly adequate hormone levels well into old age. The hormone story matters more at the extremes than it does for the typical man at any given age.

Erectile dysfunction is a more tangible factor. ED becomes substantially more common with each decade of life. A large U.S. claims-based study found that diagnosed or treated ED was most prevalent among men in their sixties.⁸ A Finnish population study demonstrated the impact clearly: moderate and complete erectile dysfunction had a strong independent effect on how often men had intercourse, even after accounting for age and whether the man had a partner. Mild ED, interestingly, had almost no measurable impact on frequency.⁹ The risk of complete ED was about four and a half times higher at age 60 than at 50, and roughly 21 times higher at 70 than at 50.⁹

Beyond hormones and erections, general health accumulates as a factor. Cardiovascular disease, diabetes, obesity, joint problems, and the medications used to treat them all contribute. A man’s mental health matters too. Depression reduces desire, and stress from work or caregiving responsibilities can crowd sex out of a couple’s routine even when desire and physical function remain intact.

Relationship Duration Matters More Than You Might Think

One of the strongest predictors of how often a man has sex is not his age, his testosterone, or his fitness level. It is how long he has been with his partner. Analysis of German panel data found that the biggest drop in intercourse frequency happens early in a relationship, and that neither moving in together nor getting married independently changed the trajectory after that initial decline.¹⁰ The “honeymoon effect” is real, but it fades regardless of the legal or living arrangement involved.

This means that when you look at age-based frequency averages, some of what appears to be an age effect is really a relationship-duration effect. Men in their twenties are more likely to be in newer relationships or to be dating, both of which come with higher frequency. Men in their forties are more likely to be a decade or more into a partnership. Separating these two effects is genuinely difficult, and most of the large surveys that produce the headline frequency numbers do not fully untangle them. If you are in a long-term relationship and notice that sex has become less frequent compared to your first year together, that pattern is nearly universal and should not automatically be interpreted as a sign that something is wrong.

The Generational Shift Among Younger Men

The declining frequency numbers among men under 35 are not just about individual aging. Something has changed between generations. Americans born in the 1990s were more than twice as likely to report having had no sexual partners since turning 18 compared to those born in the 1960s, when measured at the same age.¹¹ A study tracking U.S. men from 2006 to 2019 confirmed that while overall rates of sexual inactivity were relatively stable across the full time period, men born between 2000 and 2004 had significantly higher rates of sexual inactivity than previous birth cohorts at the same age.¹²

German data has shown a similar pattern. Representative surveys in 2005 and 2016 found that younger and middle-aged men living without a partner had become less sexually active and reported less sexual desire compared with the same demographics a decade earlier.¹³ The trend is not confined to the United States.

Researchers have proposed many explanations for this generational decline: higher rates of living with parents, increased use of digital entertainment and pornography, greater economic precariousness among young adults, shifting social norms around dating, and the rise of dating apps that paradoxically may make casual encounters both more accessible and more anxiety-inducing. No single cause has been definitively established. What is clear is that the averages reported for “men in their twenties” are lower today than they were 20 years ago, and that this reflects a genuine cohort effect rather than just the normal ebb of a particular survey year.

How Reliable Are the Numbers

All the data discussed here comes from self-reported surveys, and that is worth pausing on. Sex is one of the most socially loaded topics a researcher can ask about, and people do not always answer honestly. Research on social desirability bias in sexual surveys has found that misreporting is common and sometimes extreme. People tend to inflate culturally approved behaviors and downplay disapproved ones, and this happens even when surveys are anonymous.¹⁴

One well-documented example: in virtually every large survey, men report more opposite-sex partners than women, which is a mathematical impossibility in a closed population. A British national probability survey found that men reported roughly 14 lifetime partners on average while women reported about 7. Researchers determined that estimation strategies (men rounding up, women rounding down) and attitudes about what is socially acceptable accounted for nearly two-thirds of the gap.¹⁵ If men inflate partner counts, it stands to reason that frequency reports may also tilt upward, though the degree of inflation for frequency specifically is harder to pin down.

None of this means the surveys are useless. The trends they capture, especially within the same survey methodology repeated over years, are likely real even if the absolute numbers are soft. When the General Social Survey shows frequency declining over two decades, the decline almost certainly happened, even if the starting point was slightly overstated. Treat the specific numbers as useful approximations rather than precise measurements.

Does Sexual Frequency Affect Health

Men often wonder whether having more or less sex actually changes their health outcomes. Two areas have received the most research attention: cardiovascular health and prostate cancer risk.

On the cardiovascular side, a study examining the relationship between sexual frequency and both cardiovascular disease incidence and death from any cause found a nonlinear pattern. Risk decreased as frequency rose, bottoming out in the range of roughly once to twice a week. At frequencies well above twice a week, the protective association weakened and eventually disappeared, producing a slightly U-shaped curve.¹⁶ The researchers could not prove that sex itself causes the benefit; healthier men tend to have more sex, so the direction of causation is hard to establish.

The prostate cancer connection is more thoroughly studied. A large cohort study following men for over a decade found that those who ejaculated 21 or more times per month had a roughly 20% lower risk of being diagnosed with prostate cancer compared to men who ejaculated four to seven times per month.¹⁷ This association held for ejaculation frequency recalled from ages 20 to 29 and from ages 40 to 49, and was strongest for lower-risk forms of prostate cancer. An earlier analysis from the same cohort had found a similar direction but more modest effect.¹⁸ A dose-response meta-analysis pooling results across multiple studies concluded that moderate ejaculation frequency, about two to four times per week, was linked to a modestly lower prostate cancer risk.¹⁹

These findings are worth knowing, but they should not be treated as medical prescriptions. Ejaculation frequency is a marker that likely correlates with many other aspects of a man’s health and lifestyle. The associations are real, but no doctor would tell a man to increase his sexual frequency specifically to prevent prostate cancer. The evidence is suggestive, not definitive enough for that.

What “Average” Hides

Averages are tidy, but sexual frequency is not evenly distributed. In any age group, you have men who are having sex daily and men who have not had sex in over a year. The distribution is heavily skewed: a relatively small group of very sexually active men pulls the average up, while a growing share of sexually inactive men pulls it down. This is especially true among younger men today, where the data shows simultaneous increases in the share who are sexually inactive and decreases in the share having sex weekly or more.

Relationship status is the single biggest sorting variable. A partnered man in his fifties may well be having sex more often than an unpartnered man in his twenties. Health, desire, partner availability, and a dozen other factors all create enormous variation within each age bracket. The age-based averages are real in the aggregate, but they describe a statistical population, not a benchmark any individual man should measure himself against. If your own frequency feels satisfying to you and your partner, it is the right frequency, regardless of where it falls on a national survey curve.

Cross-Cultural Patterns

Most of the data discussed here comes from the United States and Western Europe, so it is worth noting that cross-cultural variation exists. The Global Study of Sexual Attitudes and Behaviors, which surveyed adults over 40 in 29 countries, found clear and consistent patterns across cultures: sexual desire and activity were widespread in middle and older age everywhere, and sexual dysfunction became more common with age, especially in men.⁴ But there were also major between-country differences in reported frequency and satisfaction, reflecting cultural norms, religious influences, economic conditions, and healthcare access. A man in his forties in one country might report patterns more typical of a man in his thirties or his fifties elsewhere. The age-based curve slopes downward everywhere, but its starting point and steepness are not universal.

The German surveys that documented declining desire among younger men raise the possibility that the generational shift is not uniquely American, either.¹³ Whether the same pattern holds in non-Western countries is harder to say. Sexual behavior research is heavily concentrated in high-income Western nations, and data from sub-Saharan Africa, South Asia, and East Asia tends to focus on reproductive health outcomes rather than frequency surveys. The global picture is incomplete, and generalizing from American or European data to all men everywhere should be done cautiously.
