How Often Do Couples Have Sex? What the Data Says
Around once a week on average, and falling. What the survey data shows by age, why the average is a bad target, and when frequency is genuinely worth worrying about.
About once a week. That is the short answer, and it is the number most people are looking for when they search this.
The longer answer is more useful, because the average conceals an enormous range, and because “below average” is not a diagnosis.
The numbers
The best long-running data on this comes from the General Social Survey, which has asked Americans about sexual frequency since the 1980s. The current figure is roughly 54 times a year, which works out at a little over once a week.
That number has been falling for decades. In 1990 the same survey produced an average closer to 73 times a year. The Institute for Family Studies has tracked this decline in detail in its analysis of what it calls the sex recession, and the share of married adults reporting weekly sex has slipped from around 59% in the late 1990s to under half in the most recent decade.
Roughly by age, the pattern looks like this:
| Age group | Typical frequency |
|---|---|
| Under 40 | About once a week |
| 40 to 59 | Two to three times a month |
| 60 and over | Once or twice a month |
Researchers generally estimate that somewhere between 15% and 20% of married couples have sex fewer than ten times a year, which is the usual working definition of a sexless marriage.
Why the average is a bad target
Two reasons.
The distribution is wide and lumpy. “Once a week on average” describes almost nobody’s actual year. Real couples have periods of several times a week and periods of nothing much, usually tracking illness, work, small children, and whether anybody is sleeping.
More is not straightforwardly better. This is the finding worth knowing. Research covered by the Society for Personality and Social Psychology found that while frequency is associated with wellbeing, the association stops at about once a week. Beyond that point, more sex was not associated with more happiness.
That result is widely misread as a prescription. It is not. It means the relationship between frequency and satisfaction is not linear, and that a couple having sex twice a month who are both content with that are not doing worse than a couple managing four times a week and keeping score.
What actually predicts satisfaction
Not frequency, at least not on its own. The things that show up more reliably:
Whether you are both content with it. A couple at twice a month who both want twice a month are fine. A couple at twice a week where one of them wants more are not. The gap matters, not the number.
Whether it can be talked about. Couples who can raise the subject without it becoming a row tend to sort it out. Couples who cannot tend to let it drift for years.
Whether there is other physical affection. Frequency usually falls off a cliff in couples who have also stopped touching each other in non-sexual ways. The general closeness tends to go first.
Whether it is initiated by both of you. Long stretches where one person always initiates and the other always responds tend to end with the initiator giving up.
The stages where it drops, predictably
Worth knowing, so you do not treat a normal phase as a crisis.
The first two years. It falls from wherever it started. This is not a sign of anything.
Small children. The single biggest factor for most couples, and the one that most reliably recovers.
Long working stretches. Fatigue is a bigger factor than desire in most cases.
Illness, medication and menopause. Frequently the actual cause, and frequently never mentioned, because couples assume it is about the relationship. Antidepressants and hormonal changes both have well documented effects. Worth raising with a doctor before deciding it is a marriage problem.
When it is worth worrying about
Frequency alone is not the signal. These are.
- One of you is unhappy about it and has not been able to say so.
- It stopped suddenly rather than tapering, with no obvious cause.
- The non-sexual affection has gone too.
- One of you is avoiding it and neither of you knows why.
- It has become the subject of an argument that repeats without resolving.
That last one is the clearest. A repeating unresolved argument about sex is rarely about sex, and it is the sort of thing a counselor can unpick faster than you can.
If you want it to change
Start with the non-sexual part. Couples who have stopped touching altogether generally need to fix that first. It is a lower barrier on a bad week and it tends to bring the rest with it.
Raise it outside the bedroom, and not at night. A conversation about sex conducted at the point of rejection goes badly every time.
Be specific about what you want, not about what is missing. “I miss you” works. “We never have sex any more” starts a defence.
Look at the practical causes first. Sleep, medication, workload, whether you are ever alone in the house. These are more often the cause than desire is.
There is more on the practical side in how to spice up your marriage, and if the two of you simply want different amounts, mismatched libido deals with that directly.
Frequently asked questions
How often do married couples have sex on average? About once a week, or roughly 54 times a year according to General Social Survey data. The figure has been falling for several decades.
Is once a month normal? It is well within the range, particularly over 40 or with young children. Whether it is a problem depends on whether you are both content with it.
What counts as a sexless marriage? The usual definition is fewer than ten times a year. Researchers estimate this applies to between 15% and 20% of married couples.
Does more sex mean a happier relationship? Up to a point. Research suggests the association between frequency and wellbeing levels off at about once a week, and more than that is not linked to greater happiness.
Why has our frequency dropped? The most common causes are practical rather than emotional: small children, fatigue, workload, medication and hormonal change. Those are worth ruling out before concluding it is the relationship.
When should we worry about it? When one of you is unhappy and cannot say so, when it stopped abruptly, when non-sexual affection has also gone, or when it has become a repeating argument.
