The average man has sex about once a week, though that number shifts significantly depending on age, relationship status, and lifestyle. Across large surveys, once per week is the most consistent benchmark for adult men of all ages, but the real picture is more nuanced than a single number suggests.
Frequency by Age Group
A 2020 survey broke down how often men reported having sex at least once per week across different age ranges. Men aged 18 to 24 came in at about 37%, which is lower than you might expect for that age group. The rate jumps to roughly 50% for men between 25 and 44, then gradually declines from there. Women in the same age brackets reported similar or slightly higher weekly rates.
A study out of Dublin found a comparable pattern: among sexually active adults, 36% had sex once or twice a month, while 33% had sex once or twice a week. The takeaway is that once a week is common, but having sex a few times a month is just as normal.
How Relationship Status Changes the Numbers
Whether you’re single, living with a partner, or married makes a bigger difference than most people assume. Data from the General Social Survey shows that among men aged 20 to 39, cohabiting men have the most sex: 52% report having sex at least twice a week. Married men in the same age range come in at 42%. Single men have the least, with only 37% of those in their twenties and thirties reaching twice-weekly frequency.
This surprises people who picture marriage as the end of an active sex life. In reality, simply having a consistent partner in the same household creates more opportunity. The gap between cohabiting and married men may reflect differences in relationship length, since couples who live together without marrying tend to be in newer relationships on average.
Why Younger Men Are Having Less Sex
One of the more striking trends in recent years is that young men are having less casual sex than previous generations. Researchers at Rutgers University identified several specific factors driving this shift, and they’re not what most people guess. Financial insecurity and student debt, for instance, don’t appear to explain the decline. Neither does watching more television.
The single biggest factor is a decrease in drinking. Reduced alcohol consumption alone accounts for more than 33% of the drop in casual sex among young men. Daily video gaming explains about 25% of the change: men who game every day have less than half the odds of having casual sex compared to men who never game. Living with parents explains another 10% or so, with those men having only about 63% of the odds of casual sex compared to men living on their own.
Researchers frame this as part of a broader pattern of delayed adulthood. Younger generations are more individualistic and more engaged in online social networks, but less socially active in person. The result is a measurable drop in sexual activity that shows up clearly in national surveys.
What Frequency Means for Satisfaction
If you searched this question because you’re wondering whether your own frequency is “enough,” the research offers some reassurance. A study published through the American Psychological Association analyzed couples and found that 86% fell into a profile where both partners were highly satisfied and had sex just under once a week. Only about 4% of couples landed in a profile marked by infrequent sex (less than two to three times per month) and low satisfaction for both partners.
Interestingly, the remaining couples showed mixed results. About 6% had a satisfied male partner but a dissatisfied female partner, while 4% had the reverse, both at moderate frequency (somewhere between a few times a month and weekly). This suggests that frequency alone doesn’t determine happiness. How well partners’ expectations align matters just as much as, if not more than, the raw number.
Factors That Can Lower Frequency
Beyond lifestyle and relationship dynamics, several medical factors can reduce how often men have sex. Common blood pressure medications, particularly a class of water pills called thiazides, are the most frequent pharmaceutical cause of erection difficulties. Beta-blockers, used for heart conditions and high blood pressure, are the next most common culprit. Many widely prescribed antidepressants and anti-anxiety medications also carry this side effect.
Stress, sleep deprivation, and hormonal changes with age all play a role too. Testosterone levels decline gradually starting around age 30, which can reduce sex drive over decades. The drop is slow enough that most men won’t notice a dramatic shift year to year, but it contributes to the overall pattern of decreasing frequency with age. If you’re taking medication and notice a change in your sex life, that connection is well documented and worth bringing up with a provider, since alternatives with fewer sexual side effects often exist.
What “Average” Actually Looks Like
Averages can be misleading because sexual frequency isn’t evenly distributed. Some couples have sex several times a week, others once a month, and both can be perfectly content. The once-a-week figure works as a rough population benchmark, but it hides enormous variation. A man in his late twenties living with a partner will typically land well above that average. A single man in his early twenties or a married man in his fifties may fall below it.
The most useful finding across all this research is that satisfaction doesn’t track neatly with a specific number. Couples who have sex once a week and couples who have sex three times a month report similar levels of happiness, as long as both partners feel the frequency works for them. The “right” number is the one where neither partner feels consistently deprived or pressured.
