Couples in their 20s have sex about once or twice a week on average. The General Social Survey puts the number at roughly 84 times per year for adults aged 18 to 29, which works out to a little over 1.5 times per week. Married couples under 30 report even higher numbers, averaging about 109 times per year, or just over twice a week.
That said, averages only tell part of the story. There’s a wide range of normal, and the numbers have been shifting downward in recent years.
What the Surveys Actually Show
The clearest picture comes from large national surveys that ask people directly about their sexual activity. Among adults aged 25 to 34, about half of men and 54% of women report having sex at least once a week. For the younger end of the decade (18 to 24), the numbers are a bit lower: 37% of men and 52% of women say they have sex weekly or more.
The median for married or cohabiting couples across all ages is about three times per month. Couples in their 20s tend to land above that median, but not dramatically so. If you and your partner are having sex somewhere between a few times a month and a few times a week, you’re squarely within the typical range for your age group.
Relationship Status Makes a Big Difference
Whether you’re married, living together, or dating separately has a major effect on frequency. Married and cohabiting couples consistently report more sex than people who are single, divorced, or widowed. Among married couples under 30, sexual inactivity is rare: only about 1 to 2.5% report having no sex at all in a given year.
Living together simply creates more opportunity. Shared routines, shared beds, and the comfort of an established relationship all contribute. Couples who are dating but living apart naturally have fewer chances, and their frequency tends to reflect that logistical reality more than any difference in desire.
Young Adults Are Having Less Sex Than Before
One of the most consistent findings in recent research is that people in their 20s are having less sex than the same age group did 20 years ago. A study published in JAMA Network Open tracked trends from 2000 to 2018 and found notable declines across the board.
Among men aged 18 to 24, the share reporting weekly or more sex dropped from about 52% to 37%. For men aged 25 to 34, it fell from 65% to 50%. Women aged 25 to 34 saw a similar decline, from 66% to 54%. At the same time, the proportion of young men reporting no sex at all in the past year nearly doubled, rising from about 19% to 31% among 18- to 24-year-olds.
The reasons behind this shift aren’t fully settled, but researchers point to several converging factors: more young adults living with parents, delayed marriage and partnership formation, increased screen time and digital entertainment competing for attention, and higher rates of stress and anxiety among younger generations. The decline isn’t unique to any one group. It cuts across education levels, races, and regions.
Frequency and Relationship Satisfaction
If you’re searching this topic, you’re probably wondering whether your frequency is “enough.” Research on over 2,000 couples, most of them in their 20s and 30s, offers some reassurance. The vast majority of couples (about 86%) fell into a profile where both partners were highly satisfied with their relationship and had sex just under once a week. That’s the most common pattern: not every day, not rarely, just regularly enough that both people feel connected.
A small group (about 3.6%) reported both infrequent sex (less than two to three times per month) and low satisfaction from both partners. But the interesting finding is that two other groups, making up about 10% of couples combined, had moderate frequency yet one partner was dissatisfied while the other wasn’t. This suggests that how aligned you and your partner feel about your sex life matters more than hitting a specific number. A couple having sex three times a month where both partners feel good about it is in a healthier place than a couple having sex twice a week where one person feels pressured or the other feels neglected.
What “Normal” Actually Looks Like
The honest answer is that normal spans a wide range. Some couples in their 20s have sex several times a week, others a few times a month, and both can be perfectly healthy. The numbers shift depending on how long you’ve been together (new relationships typically involve more sex), whether you live together, work schedules, stress levels, and individual differences in desire.
What the data consistently shows is that once-a-week sex is the most common frequency among satisfied couples in this age group. Going above that doesn’t seem to add much to relationship happiness, while going well below it can signal a mismatch worth talking about. The number that matters most isn’t the national average. It’s the one where both you and your partner feel satisfied.
