Most men between 18 and 59 masturbate a few times per month to a few times per week. About a quarter fall in the “few times per month to weekly” range, roughly 20% do so two to three times a week, and fewer than 20% masturbate more than four times a week. There’s no single “normal” number, but the data paints a clear picture of what’s typical.
Frequency by Age
Masturbation frequency tends to peak in younger adulthood and gradually decline with age. Men in their late teens and twenties generally report the highest rates, often several times per week. By middle age, the frequency often drops to a few times per month. Older men are the most likely to report no masturbation at all over the previous year, though plenty remain sexually active well into later life.
These are averages, not targets. Some men masturbate daily, others once a month, and both patterns are common. Relationship status, stress levels, sex drive, and overall health all shift the number in either direction.
How Culture Shapes the Numbers
Where you live influences how freely people report masturbating, which makes global comparisons tricky. Survey data from 2020 found that about 61% of British adults masturbate, with one in ten doing so at least three times a week. Around 60% of American adults reported masturbating at least once a week. In South Korea, 43% of adults reported masturbating. In many African and Asian countries, social stigma means people are far less likely to disclose the behavior at all, so reported rates run lower even if actual behavior may not differ as dramatically.
Potential Benefits for Prostate Health
One of the more striking findings in men’s health research links ejaculation frequency to prostate cancer risk. A large Harvard-based study followed tens of thousands of men over nearly two decades and found that men who ejaculated 21 or more times per month had a 31% lower risk of prostate cancer compared to men who ejaculated four to seven times per month. A separate analysis found that men averaging roughly five to seven ejaculations per week were 36% less likely to be diagnosed with prostate cancer before age 70 than men who ejaculated fewer than two to three times a week.
These studies measured total ejaculation frequency, not masturbation alone, so sex with a partner counts equally. The mechanism isn’t fully understood, but researchers suspect regular ejaculation may help clear the prostate of potentially harmful substances.
When Frequency Affects Sexual Function
For most men, masturbating regularly causes no problems. But very frequent masturbation, especially when paired with a consistent grip, speed, or pressure that differs from what partnered sex provides, can create a mismatch. The body gradually adapts to that specific type of stimulation, raising the threshold needed to reach orgasm. This is sometimes called desensitization, and it works in both directions: it can help men who tend to finish too quickly, but it can also make it harder to climax during intercourse.
Research on men in sexual relationships found that more frequent masturbation was linked to more symptoms of delayed ejaculation and more frequent feelings of finishing too late during sex. In one study of Chinese men, 25% of those who masturbated reported a gradual increase in the time it took them to ejaculate. Some men also develop difficulty maintaining an erection during partnered sex when their masturbation habits involve a very specific, hard-to-replicate pattern of stimulation.
These effects aren’t permanent. Men who notice it’s getting harder to finish with a partner can typically reverse the pattern by varying technique, reducing grip pressure, or cutting back on frequency for a period. The issue isn’t masturbation itself but a narrow, repetitive style that trains the body to respond to only one kind of stimulation.
What Actually Matters More Than the Number
The frequency that works for you depends on whether it fits comfortably into your life. A useful way to think about it: masturbation becomes a concern not at any particular number per week, but when it starts interfering with responsibilities, relationships, or your ability to enjoy sex with a partner. If it feels compulsive, meaning you’re doing it not because you want to but because you feel driven to, that’s worth paying attention to regardless of how often it happens.
Outside of those situations, the range of normal is genuinely wide. Men who masturbate daily and men who rarely do are both well within the spectrum that sexual health researchers consider unremarkable.
