It’s one of the most common quiet anxieties in any marriage: are we normal? You hear couples joke about doing it every day, or read that some scary number is “healthy,” and you look at your own marriage — once a week, twice a month, less — and wonder if something’s wrong with you, your partner, or the relationship. Let’s settle it with what the research actually says, and then explain why the number matters far less than you’ve been led to believe.

The actual averages

Across large surveys, the average married couple has sex roughly once a week — somewhere around 50 to 60 times a year. But that average hides a huge range, and the single biggest factor is age. Broadly, the research looks like this:

  • 20s and early 30s: around twice a week on average, sometimes more.
  • Late 30s: around once a week, sometimes a bit more (very roughly 70–90 times a year).
  • 40s and 50s: a few times a month.
  • 60+: once or twice a month, often less.

Frequency naturally declines with age, length of relationship, work and financial stress, and — massively — the arrival of children. A drop over the years isn’t a sign of a failing marriage; it’s the statistical norm.

Two important caveats about these numbers. First, they’re averages across whole populations, not a target. Second, people exaggerate — surveys of self-reported sex are notoriously inflated, and the impression you get from friends’ jokes or social media is even more so. You’re almost certainly comparing your honest reality to everyone else’s highlight reel.

Why the number barely matters

Here’s the finding that should take the pressure off. A widely-cited 2015 study by Muise and colleagues found that, for couples, greater wellbeing was associated with more frequent sex only up to about once a week. Beyond once a week, having sex more often was not linked to being any happier. There’s no wellbeing prize for hitting some high number.

And even that “once a week” is an average across many couples — not a rule you’ve failed if you’re under it. The honest truth from the research is consistent: sexual satisfaction predicts relationship happiness far better than sexual frequency does. A couple having genuinely good, connected sex twice a month is doing better than a couple grinding out unsatisfying sex three times a week to hit a number.

So the right question isn’t “how many times should we be doing it?” It’s “are we both happy with our sex life?” If yes, you are normal and fine, full stop — whatever the count. If no, the frequency is a symptom, not the disease.

When frequency is worth paying attention to

A number that both partners are content with is never a problem. But low or declining frequency is worth addressing when:

  • One or both of you is unhappy about it. A mismatch in how much sex each of you wants — desire discrepancy — is one of the most common couple issues and is worth talking about, not burying.
  • It’s a symptom of something fixable — erectile dysfunction, painful sex, low desire, or a medical/hormonal issue.
  • It reflects emotional distance or resentment — sex is often the first casualty of a relationship that’s drifting, and the frequency is a signal to reconnect.
  • It’s slid to almost nothing and someone’s miserable — see our guide on sexless marriage.

In other words: don’t chase a statistic, but don’t ignore real unhappiness either. The thing to track isn’t the count — it’s whether both of you feel wanted and satisfied.

The takeaway

There is no correct number of times to have sex. The averages (about once a week overall, more when you’re younger, less as you age) are descriptions of what people do, not standards you must meet — and they’re inflated by exaggeration anyway. The research is clear that beyond roughly once a week, more sex doesn’t buy more happiness, and that satisfaction matters far more than frequency.

So stop measuring yourself against a number or against other couples’ boasts. Ask the only question that matters: are we both content and feeling close? If you are, you’re normal. If you’re not, talk about it — our guide on how to talk to your wife about sex is the place to start. The conversation, not the count, is what actually improves things.
