There is no normal amount of sex for married couples in any medical sense. No health body sets a number, although large population surveys do give a rough middle point. In the United States, about 6 in 10 married adults aged 18 to 44 report having sex weekly or more. The rest report less, and plenty of happy couples sit well below that line.
How often a couple has sex shifts with age, with how long they have been together, and with health. A newlywed couple in their twenties and a couple in their sixties managing a heart condition will land in very different places, and both can be perfectly healthy. What research ties most clearly to a good relationship is whether both partners are content with how often sex happens. This guide covers the numbers, what moves them, and when a gap is worth getting help with.
How often married couples have sex: what the surveys show
The average is roughly once a week
For married adults, the middle of the range sits around once a week. A large study in JAMA Network Open used the US General Social Survey to track adults aged 18 to 44. In 2016 to 2018, 57.7% of married men and 60.9% of married women said they had sex weekly or more. Put the other way, roughly 4 in 10 married adults in that age range had sex less often than weekly.
Over a year, that adds up to dozens of times rather than hundreds. Psychology Today, summing up US survey research, puts people in their 20s at about 80 times a year. That is roughly once every four to five days. The JAMA sample stopped at age 44, and older couples report lower numbers, as the age section below shows.
Married couples versus single people
Married people generally have sex more often than unmarried people, a pattern Psychology Today describes as a buffering effect of marriage. That is a link in survey data, not proof that marrying causes more sex. Still, married couples have not escaped a wider slowdown. Between 2000-2002 and 2016-2018, weekly sex among married men fell from 71.1% to 57.7%. Among married women it fell from 69.1% to 60.9% over the same years.
The drop shows up across the whole population. By the early 2010s, Americans were having sex about nine fewer times a year than in the late 1990s. A rise in single and unmarried people cannot explain the fall among married couples, and Psychology Today says researchers still do not know why it happened.
Why survey numbers are rough
Sex surveys depend on people remembering and reporting honestly. The JAMA authors point out that their data are open to response and reporting bias. Sex itself was never defined in the survey, so one person may count only intercourse while another counts oral sex or mutual touching. The question covers the last 12 months, which invites rounding and guesswork.
Averages also hide a wide spread. Some couples have sex several times a week and others go months without it, so a middle figure describes neither group particularly well. A number like “once a week” is useful as context. It tells you where many couples land, and nothing about where you should land.
How sex frequency changes with age
Average frequency by age group
Sexual frequency drops steadily with age. The clearest married-only figures come from a survey of more than six thousand married US adults. Sociologist Vaughn Call and colleagues ran it, and the Marriage and Family Encyclopedia reports the results.
| Age group | Sex per month among married adults |
|---|---|
| 19 to 29 | About 10 to 12 times |
| 40s and 50s | About 4 to 7 times |
| 70s | Fewer than 2 times |
These figures come from a study published in 1995, and overall frequency has fallen since then. Because of that fall, read them as the shape of the slope rather than a current benchmark. Newer US data show the same slope. People in their 20s report about 80 times a year, while people in their 60s report about 20. That is a fourfold drop over four decades of life.
Sex after 60 is common
Many people stay sexually active well into later life. The American Geriatrics Society cites a large study in which 62% of women and 85% of men aged 57 to 65 had sex in the past year. Between ages 75 and 85, 17% of women and 39% of men were still sexually active.
Having a partner makes a big difference. Among people aged 75 to 85 in that study, about half of those with a partner were still sexually active. That is far above the 17% of women and 39% of men in the age group as a whole. So the oldest age bands mix couples who still have sex with people who no longer have a partner at all. That mix pulls the average down, and it says little about what a healthy older couple can expect.
Why frequency drops with age
Bodies change over the decades, and sexual problems become more common with age. Among sexually active women aged 75 to 85, about half reported low interest and 44% had vaginal dryness. By age 70, 67% of men reported trouble getting or keeping an erection. Chronic illness and medicines add to this, as the health section explains.
Age and relationship length are also tangled together. As a couple grows older, so does their relationship, which makes it hard to tell how much of the drop comes from age and how much from familiarity. Some couples settle comfortably at a lower rate and lean more on nonsexual affection, such as cuddling, kissing and touch.
How relationship length and life stage change it
The honeymoon effect fades
Yes, couples usually have less sex as the years go by, and the fastest drop comes early. In one diary study of newlyweds, couples had sex 17 or more times in their first month of marriage. By the end of the first year, the rate had fallen to about 8 times a month. The Marriage and Family Encyclopedia notes that the decline may be steepest in the first year or first few years.
Researchers often explain this with habituation. That is the way anything familiar slowly loses some of its novelty charge. It is an ordinary process and does not, by itself, mean love is fading. Eight times a month still works out to about twice a week.
Pregnancy, new babies and young children
Couples tend to have sex less often in late pregnancy and in the years after a birth. Physical recovery is one reason. After a vaginal birth, Banner Health says there is no required waiting period, but recovery typically takes about four to six weeks. Shifting hormones and breastfeeding can cause vaginal dryness, which can make penetration painful. Low desire after delivery is very common.
Then come the years of broken sleep and small children. Lack of privacy and the fatigue of child care are linked with lower frequency, and so are heavy work schedules. Some of the largest recent declines in frequency were among parents of school-aged children. A slower pace through these years is common, and on its own it is not a sign that the marriage is failing.
Long marriages
After the steep early drop, later declines tend to be gentler. Over a long marriage, many couples keep sex in their lives while putting more weight on affection, humor and companionship. Others become comfortable having very little sex and replace it with nonsexual closeness.
Mismatches are common at this stage too. About half of married Australians say they are satisfied with how much sex they have. That leaves roughly half who would change something. A long marriage with a gap in desire is ordinary, and it is often fixable once both people can talk about it.
Health conditions that change how often couples have sex
Menopause and erectile problems
Yes, health often changes how often couples have sex, and menopause is one of the biggest shifts. After menopause, up to half of women have pain before, during or after sex, according to WebMD. Falling estrogen thins and dries the vaginal tissue, which adds friction. Once sex has hurt, fear of the next time can tighten the muscles and make things worse. Lubricant helps, and pain that keeps coming back is worth raising with a doctor.
Erectile dysfunction (ED) means trouble getting or keeping an erection firm enough for sex, and it follows a similar age curve. The NIDDK, part of the US National Institutes of Health, says about 40% of men are affected at age 40. By age 70, the NIDDK puts the share at 70%, close to the 67% in the geriatrics study cited earlier. ED often has physical roots, too. Conditions that affect blood vessels, nerves or hormones can lead to it, including high blood pressure, heart disease and low testosterone. That makes new ED a good reason to get a heart health check.
Medications, depression and stress
Medicines are an overlooked cause of low desire. Harvard Health lists SSRI and SNRI antidepressants among the most common drugs tied to low libido. Beta blockers, diuretics, antihistamines, opioid painkillers and hormonal contraceptives can also dampen desire or arousal. A doctor may be able to adjust the dose or timing, or switch to another drug. Stopping a prescription on your own carries its own risks, so talk to the prescriber before changing anything.
Mental health matters as much as hormones. The NHS lists stress, anxiety and depression among the main causes of a low sex drive. Depression can lower desire, and some of its treatments can too. A good conversation with a doctor therefore covers the condition and the medication together.
Chronic illness and disability
Long-term conditions such as heart disease, diabetes, an underactive thyroid and cancer can all reduce sex drive. Pain, tiredness and treatment side effects make it harder still. Drinking too much alcohol is on the NHS list as well.
Some couples adapt by changing when and how they have sex rather than giving it up. They might pick times of day when energy is higher, or use positions that put less strain on a sore back or joint. Others put more weight on touch, massage and oral sex. A doctor, physical therapist or sex therapist can help fit these changes to a specific condition.
Why there is no universal standard
More sex stops adding happiness at about once a week
No one can give you a right number because the research does not point to one. Its best-known finding is a plateau rather than a target. Writing in The Conversation, researchers explain that relationship satisfaction rises with frequency only up to about once a week. Medical News Today adds that no research shows more frequent sex beyond that point raises satisfaction.
One experiment tested the idea directly. Couples were asked to double how often they had sex for three months. They did have more sex, but they ended up in lower moods and enjoyed sex less than couples who kept their usual pace. Being told to have more sex seems to drain some of the pleasure from it.
The once-a-week plateau comes from surveys of groups, so it shows a link rather than a cause. Happier couples may simply have more sex, instead of sex making them happier. The doubling experiment is stronger evidence on one narrower point: pushing couples above their usual pace did not make them happier.
Desire differs from person to person
Sex drive varies widely between people, and it changes across one person’s life. Stress, hormones, pregnancy, medicines and illness all move it up or down. No test result marks a “normal” libido. The NHS advice is simply to see a GP if you are worried about your sex drive.
At one end of the range are asexual people, who may feel little or no sexual attraction. Asexuality is an umbrella term that covers a spectrum. It includes demisexual people, who feel attraction only after a strong emotional bond. Asexual people can and do form romantic and intimate relationships.
Satisfaction is the better yardstick
Couples tend to be happiest when they have sex about as often as they both want. The real question is fit between two people. Picture two hypothetical couples to see the difference. Couple A has sex once a month, and both partners are content. Couple B has sex three times a week, but one partner often goes along just to keep the peace.
By any survey average, Couple B looks healthier. By the measure that predicts well-being, Couple A is in better shape. Low-sex marriages can work well when both people chose that rhythm. The Gottman Institute, a couples research and therapy group, says a sexless marriage is only a problem if it causes distress to one or both partners.
Myths and evidence about married sex
Several popular beliefs about married sex turn a group average into a personal rule. Here is how they hold up against the research.
| Myth | What the evidence says |
|---|---|
| Married couples should have sex at least once a week | No health body sets a number. About 4 in 10 married adults aged 18 to 44 report less than weekly sex. |
| More sex always means a happier marriage | Satisfaction rises with frequency only up to about once a week. |
| Couples who double their sex will feel closer | In one experiment, couples who tried it ended up in lower moods and enjoyed sex less. |
| Sex stops in later life | In one large study, 85% of men and 62% of women aged 57 to 65 had sex in the past year. |
| A drop after the first year means something is wrong | Frequency usually falls fastest in the first year or first few years of marriage. |
| Low desire is all in your head | Medicines, menopause, diabetes and heart disease can all lower it. |
| A sexless marriage is always an unhappy one | A sexless marriage is only a problem if it causes distress to one or both partners. |
The once-a-week rule at the top of the table is the hardest myth to shake, because comparison feels natural. Yet couples feel happier simply when they believe they have more sex than other couples. That makes measuring yourself against friends or surveys a poor guide. The more useful comparison is between what you have and what you both want.
When the amount becomes a problem, and what to do
What counts as a sexless marriage
There is no scientific definition of a sexless relationship. One clinical definition, cited by the Gottman Institute, is sex fewer than 10 times a year, or less than once a month. Everyday Health reports a 2018 study of almost 18,000 US adults. In it, a little over 15 percent of married people had not had sex in the past year. Among married adults aged 57 to 85, another study found that 40 percent had not had sex in the previous year.
So a low-sex or no-sex marriage is far from rare. Whether it is a problem depends on whether both partners are content with it.
Handling a desire mismatch
Wanting different amounts of sex is called desire discrepancy, and it is common in relationships. It is rarely solved by one partner simply giving in, which tends to breed resentment on both sides. These steps tend to help:
- Talk outside the bedroom. Pick a calm moment and describe what you miss or feel, instead of keeping score.
- Look for causes first. Check for pain, medicine side effects, exhaustion or depression before blaming the relationship.
- Plan sex when time is the problem. Couples who struggle to find time may benefit from scheduling it.
- Widen what counts. Touch, massage and solo or mutual masturbation can bridge a gap in drive.
- Rebuild closeness step by step. Gottman therapists work on emotional connection and nonsexual touch before reintroducing sex.
A sexless pattern often builds slowly through avoidance. One partner stops asking, the other stops offering, and touch of any kind starts to feel loaded. Breaking that cycle usually starts with affection that carries no expectation of sex.
When to see a doctor or sex therapist
See a doctor if sex hurts, if desire or erections change suddenly, or if a new medicine seems to have changed things. The NHS also advises seeing a GP if your sex drive does not return after pregnancy. These are medical questions, and many have treatments.
A sex therapist helps when the issue is the pattern between you, such as resentment, avoidance or a long-running mismatch. Sex therapy is talk therapy, often with homework such as communication exercises. Costs vary, and insurance may not cover it. In the US, the American Association of Sexuality Educators, Counselors and Therapists (AASECT) runs a referral directory. A couples therapist is another option when sex is one strand of wider conflict.
Get help sooner if either partner feels pressured into sex. Sex that one person does not want is a problem at any frequency.
Frequently asked questions
How often should a married couple have sex?
As often as both partners want, since no health authority sets a number. Research offers one reference point: relationship satisfaction rises with frequency up to about once a week, then levels off. Among married US adults aged 18 to 44, about 6 in 10 report weekly sex or more. Plenty of happy couples have less, and some have more.
Is once a month a sexless marriage?
Not by the usual definition, although it comes close. A sexless marriage is most often defined as sex fewer than 10 times a year. Once a month is about 12 times a year, so it sits just above that line. There is no scientific cut-off, though. A low number matters only if it bothers one of you.
How often do 60 year olds have sex?
US survey research puts people in their 60s at about 20 times a year on average, which is less than twice a month. That average includes people without a partner. In one large study of adults aged 57 to 65, 85% of men and 62% of women had sex in the past year.
Are sexless marriages common?
They are fairly common, especially in later life. A 2018 study of almost 18,000 US adults found that a little over 15 percent of married people had not had sex in the past year. One study of married adults aged 57 to 85 found that 40 percent had not had sex in the previous year.
What is considered a lot of sex in a marriage?
In a survey published in 1995, married people in their 40s and 50s averaged about 4 to 7 times a month. Frequency has fallen since then, so sex several times a week is well above typical for midlife today. That frequency is not a problem in itself, and it becomes one only if a partner feels pressured, if sex hurts, or if it feels compulsive and causes distress.
The bottom line
The normal amount of sex for married couples is a range, not a rule. Weekly sex is roughly the middle for younger married adults, and the number then drifts down with age, the years together, new babies and health changes. None of that makes a lower number unhealthy.
The better test is simple and personal. Do you both feel okay with how often you have sex, and does it feel wanted? If yes, the survey figures are just trivia. If one of you is unhappy, start with an honest talk and check for medical causes such as pain, medicines or depression. Then bring in a doctor or sex therapist when the gap does not close on its own.
