Yes, masturbation is a normal, healthy part of sexual development and carries no serious side effects. Major medical institutions, including the Cleveland Clinic, describe it as a natural way to explore your body, experience pleasure, and release sexual tension. There is no credible scientific evidence that it causes physical or mental harm.
Physical and Mental Health Benefits
Masturbation does more than just feel good. When you reach orgasm, your brain releases a surge of dopamine (the chemical behind feelings of reward and pleasure) along with oxytocin (which promotes relaxation and bonding). These natural chemical shifts translate into real, measurable benefits: reduced stress, improved mood, relief from aches and tension, and better sleep. The sleepiness you might feel afterward isn’t just in your head. Your body also releases prolactin at orgasm, a hormone directly linked to drowsiness.
For women, orgasm from masturbation can ease menstrual cramps, back pain, headaches, and joint aches. The dopamine and serotonin released during orgasm act as natural pain relievers, which is why some people find it more effective than over-the-counter painkillers during their period. Masturbation during pregnancy is also safe and can help relieve lower back pain and release built-up sexual tension.
In older adults, regular masturbation may reduce vaginal dryness and decrease pain during intercourse. One study found that married women who masturbate reported more orgasms, higher self-esteem, increased sexual desire, and greater satisfaction with both their marriage and sex life.
Possible Benefits for Prostate Health
For men, frequent ejaculation appears to lower the risk of prostate cancer. A large Harvard study followed more than 29,000 men and found that those who ejaculated 21 or more times per month had a 31% lower risk of prostate cancer compared to men who ejaculated 4 to 7 times per month. A separate Australian study found that men who averaged about 5 to 7 ejaculations per week were 36% less likely to be diagnosed with prostate cancer before age 70. Ejaculation from masturbation counts the same as ejaculation from sex.
Common Myths That Aren’t True
Many of the fears people have about masturbation come from centuries-old myths with zero scientific support. Masturbation does not cause blindness, hair loss, hairy palms, mental illness, erectile dysfunction, infertility, a decreased sperm count, or shrinkage or curvature of the penis. None of these claims hold up under research.
Some of these myths have surprisingly bizarre origins. In the late 1890s, John Harvey Kellogg invented corn flakes partly as a bland food he believed would curb sexual desire and discourage masturbation. There was, of course, no science behind the idea then or now.
Minor Physical Issues to Be Aware Of
While masturbation doesn’t cause serious side effects, a few minor physical issues can come up with rough or very frequent stimulation. Skin chafing or irritation is the most common, and it’s easily avoided by using lubrication and a lighter touch. Some men who consistently grip very tightly may find that partnered sex feels less stimulating by comparison, simply because they’ve trained their body to respond to a very specific type of pressure. This isn’t permanent damage. Varying your technique and reducing grip intensity typically resolves it over a few weeks.
If you use toys, cleaning them after each use is important to prevent bacterial buildup. Beyond that, there are no real physical risks.
When It Could Become a Problem
Masturbation itself is not harmful, but like many behaviors, it can become compulsive in rare cases. The World Health Organization’s diagnostic guidelines recognize compulsive sexual behavior as a pattern where someone repeatedly fails to control sexual urges over a period of six months or more, and where the behavior causes real disruption to their life.
The key signs that masturbation has crossed from healthy to problematic include: it has become so central to your daily routine that you’re neglecting responsibilities, health, or personal care; you’ve tried many times to cut back but can’t; you keep doing it despite clear negative consequences like relationship problems or issues at work; or you continue even though it no longer brings you much satisfaction. All of these criteria need to be causing genuine distress or impairing your ability to function.
One important distinction: feeling guilty about masturbation purely because of moral or cultural beliefs does not, by itself, mean you have a problem. Guilt rooted in shame is different from a behavior that’s actually disrupting your life. The diagnostic criteria specifically note that distress coming entirely from moral disapproval of sexual behavior is not enough to qualify as compulsive sexual behavior.
How Often Is Normal
There is no specific number of times per day, week, or month that qualifies as “too much.” Some people masturbate daily, some a few times a week, some rarely, and some never. All of these are normal. The right frequency is whatever fits comfortably into your life without interfering with your relationships, work, or daily responsibilities. If it feels good, isn’t causing problems, and you’re not doing it to avoid dealing with something else, you’re fine.
