How Often Do Couples Have Sex? The Real Numbers, by Age and Marriage

How often do couples have sex?

How often couples have sex varies widely, and it falls with age. In US national data, people in their 20s average more than 80 times a year, about 60 times by age 45 and about 20 by age 65. In 2024, 46 percent of married adults aged 18 to 64 reported having sex weekly or more.

So the honest answer to "how often do couples have sex?" is: more in the early years, less with each decade, and on a slow decline across the whole country.

Here are the key numbers at a glance, each from a source you can open.

Averages tell you about the country. They tell you very little about your bedroom. Two couples at "twice a month" can be in completely different places: one content, one with a partner quietly hurting. That is why the most useful number is one you won't find in a survey: the number each of you would pick, and how far apart those are.

That gap is hard to say across a pillow. Adoree, an AI relationship assistant, talks to each partner privately, by voice or text, so you can each say what you actually want before you have to say it to each other.

Average sex frequency by age

Sex frequency peaks in the mid-20s and declines steadily with age. In General Social Survey data covering more than 26,000 American adults, people in their 20s had sex more than 80 times a year, about 60 times a year by 45 and about 20 times a year by 65. After the peak at about age 25, frequency fell roughly 3.2 percent a year.

Those figures come from Jean Twenge, Ryne Sherman and Brooke Wells, whose 2017 study in Archives of Sexual Behavior analysed 26,620 GSS respondents from 1989 to 2014. The age breakdown below is from San Diego State University's summary of the study.

For younger adults there is a more recent picture. A 2020 JAMA Network Open study of GSS respondents aged 18 to 44 compared 2000-2002 with 2016-2018:

The same study found the share of men aged 18 to 24 reporting no sex in the past year rose from 18.9 to 30.9 percent. For women that age, the change (15.1 to 19.1 percent) was not statistically significant.

How often do married couples have sex?

Married couples have sex more often than unmarried adults on average, largely because people without a steady partner have sex less often. In 2024, 46 percent of married adults aged 18 to 64 reported sex weekly or more, compared with about 34 percent of unmarried adults. But the married advantage is shrinking, because frequency is falling inside marriages too.

The longer view says the same thing. Twenge's team found that Americans who were married or living together had sex about 16 fewer times a year in 2010-2014 than in 2000-2004, while frequency among the unpartnered stayed steady. Notably, the decline was not linked to longer working hours or more pornography use, and it was largest among people in their 50s and parents of school-age children.

Survey data on other measures points the same way. The National Survey of Sexual Health and Behavior found that 28 percent of adults aged 18 to 49 reported no penile-vaginal intercourse in the past year in 2018, up from 24 percent in 2009, with declines across every form of partnered sex the survey asked about.

How often should couples have sex?

There is no number couples should hit. The best evidence suggests that, for people in relationships, wellbeing rises with sexual frequency up to about once a week and then levels off. Trying to force more than feels natural can backfire. The right frequency is the one both partners feel good about.

The once-a-week finding comes from Amy Muise, Ulrich Schimmack and Emily Impett, who looked at three studies with 30,645 people. The link between sex and wellbeing showed up only for people in relationships, it ran through relationship satisfaction, and above once a week it was no longer significant.

Then there is the experiment. Researchers at Carnegie Mellon randomly assigned married couples to either carry on as usual or double their weekly frequency for three months. The instructed couples did have more sex. Their happiness dipped slightly, and they reported lower desire and less enjoyment. The researchers suspected the problem was being told to, rather than choosing to.

Put those together and "how often should we?" turns into a better question: how often would we both want to, if nothing were in the way?

When you want different amounts

Wanting different amounts of sex is one of the main reasons couples seek professional help, and it is workable. Researchers call it sexual desire discrepancy. People who deal with it together with their partner, by talking or doing something else together, report higher sexual and relationship satisfaction than those who handle it alone.

In a 2020 study of 229 people in long-term relationships, Laura Vowels and Kristen Mark identified 17 strategies people use when desire doesn't match, grouped into five kinds: disengaging, communicating, doing something alone, doing something else together, and having sex anyway. Partnered strategies were linked with higher sexual and relationship satisfaction than individual ones. None of the strategies was linked with desire itself, which is a useful reminder: the realistic goal is a gap you handle well together.

The other half of this is that both people are usually hurting. The higher-desire partner often hears every no as rejection of them. The lower-desire partner often feels like sex has become a debt. Both stories are true from where they sit, and neither person can see the other's from inside the bed.

How to talk about how often you have sex

Talk about it outside the bedroom, lead with what you want rather than what is missing, and be curious about your partner's side before defending your own. Research suggests the quality of these conversations matters more than how often you have them.

That comes from a 2022 meta-analysis of 93 studies and 38,499 people in relationships. Sexual communication was linked with both relationship satisfaction (r = .37) and sexual satisfaction (r = .43), and the quality of that communication mattered more than its frequency.

A few ways in that tend to land:

• Pick a neutral moment. A walk, a drive, a Sunday morning. Not right after a no.
• Open with the good. "I miss being close to you" starts a conversation. "We never have sex anymore" starts a defence.
• Ask before you explain. "What has it felt like for you lately?" Then actually listen.
• Talk about the conditions as well as the count. Tiredness, stress, timing, who usually initiates. The number is often a symptom.
• Agree on one small thing. A ten-minute check-in a week, or one evening with phones in another room.

If the first conversation feels impossible, rehearsing it helps. You can talk it through privately with Adoree first, and if your partner does the same on their side, Adoree can help you both see where your two versions actually differ.

What "normal" really means

Normal is a wide range. The national averages describe millions of very different relationships at once: newlyweds and couples married forty years, parents of newborns and empty nesters, people with chronic illness and people training for marathons. Your number reflects your life right now, and it will move.

What the research keeps pointing at is satisfaction. About once a week is where the wellbeing benefit tops out on average, and couples who feel close, talk well and handle their differences together tend to be more satisfied wherever their number sits. If you are both happy, you are normal. If one of you is not, the next step is a conversation.
