How does your frequency compare to the real data?

Yes. A third of adults in the NSSHB 2021 sample (34.3%) hadn't masturbated in the past year, and among women the figure is 43.5%, which is close to the median rather than an outlier. People give all sorts of reasons: preference, faith, a relationship that covers it, or plain lack of interest. Whatever the reason, the data doesn't support the idea that everyone does it. The sex statistics page has the wider picture on partnered sex and the rest of the survey.

Yes, though it puts you in a small group. In the NSSHB 2021 data 9.9% of men and 0.5% of women report masturbating almost every day. Being at the tail of a distribution isn't a diagnosis; that needs distress, injury from friction or interference with work or relationships, and without those daily is simply the top of the normal range. Men aged 25 to 29 are the peak group, with 44% at two or more times a week, and the sex frequency calculator shows how that compares with partnered sex at the same age.

Yes, but more slowly than most people assume. Men peak between 25 and 29 and taper from there, and women peak across their 20s and 30s. Among the over-70s, 28% of men and 12% of women had masturbated in the past month. At both ends of adulthood, 14 to 24 and over 50, solo sex is the most frequent sexual behaviour people report, ahead of sex with a partner, mostly because those are the years when a partner is least likely to be available.

Yes, and it's the usual state of affairs rather than a sign something's wrong. The 2017 Archives of Sexual Behavior study of more than 15,000 people found that women in particular masturbate most when partnered sex is frequent and satisfying, so the two aren't competing. For men it's more often the other way round, rising when partnered sex falls away. Both are ordinary. If a partner is uncomfortable about it, that's a conversation to have, not a clinical problem, and the desire gap calculator shows how common mismatched desire is in the first place.

In the short term, yes, and mostly in the direction people don't expect. Ejaculating more often lowers the concentration of sperm per millilitre but leaves the total number of motile sperm about the same, while going more than five days without is linked to poorer motility and more DNA damage. Some IVF and IUI studies find better results when men ejaculate every day or two during the fertile window, and fertility clinics have largely stopped asking for long abstinence beforehand. Over the long run, how often a healthy man masturbates doesn't appear to change his fertility.

Compulsive sexual behaviour disorder went into the ICD-11 in 2022, and its definition is about control, not count: a persistent failure to rein in sexual behaviour despite distress or harm. Someone who masturbates every day without distress, without it touching their relationships and without it affecting their work doesn't meet the criteria however high the number. Most people who worry they do it too much don't have a disorder. They have shame, usually inherited, and that's a different problem with a different fix.

The two go together: people who watch pornography masturbate more often. Which one drives the other is hard to pin down, and probably runs both ways. For a small group, pornography becomes compulsive and is part of a pattern of masturbation that distresses them, and in people who already struggle with impulse control its constant availability can keep the pattern going. In the general population the research doesn't find that pornography causes frequency problems on its own.

Only for a few minutes. Testosterone rises around arousal and orgasm and drops back to baseline within minutes to hours, which is about as clinically meaningful as your heart rate going up on the stairs. The study the "no-fap" forums lean on, from 2003, found a one-day spike on day seven of abstinence and nothing after that, and the paper was retracted in 2021. There's no evidence that how often you masturbate moves your long-term testosterone level in either direction.

Modest ones, on the evidence. Rider and colleagues followed 31,925 men for their 2016 paper in European Urology and found that those ejaculating 21 or more times a month had a 19% lower risk of prostate cancer than those at 4 to 7 times, after adjusting for the obvious confounders; the suggested mechanism is that the prostate gets flushed of things that shouldn't sit in it. Orgasm itself brings the short-term effects you'd expect from a release of endorphins and oxytocin: less stress, better sleep, some pain relief. All of that describes populations, not a prescription for you.

A big one. Where a religion forbids it, reported frequency drops for two reasons at once: some people really do abstain, and some people stop telling surveys the truth. The NSSHB shows lower frequency among the more observant, and that's the main reason comparisons between countries are so unreliable. So the US figure of 34.3% reporting none in the past year is almost certainly a mix of genuine abstinence and under-reporting, so if you're comparing yourself to it, remember that the "average" was set partly by people who weren't saying.
