No, masturbation is not bad for you. It’s a normal, healthy part of sexual development, and it doesn’t cause any serious side effects. Major medical institutions, including the Cleveland Clinic, describe it as a natural way to explore your body and experience pleasure. The real question isn’t whether masturbation is harmful in general (it isn’t), but whether certain patterns or habits around it could become a problem for some people.
What Happens in Your Body
When you orgasm, your brain releases a flood of feel-good chemicals. Endorphins create a natural high that can leave you feeling relaxed, happy, and sleepy. Your body also releases prolactin, a hormone that produces feelings of satisfaction and sexual gratification. These effects linger for a while after orgasm, which is why many people feel calm or drowsy afterward.
Dopamine, the brain’s main reward chemical, spikes during orgasm and then drops below its normal baseline shortly after. That temporary dip can leave some people feeling low-energy or flat for a brief period, but levels return to normal relatively quickly. This cycle is completely ordinary and not a sign of harm.
Proven Health Benefits
Masturbation does more than feel good in the moment. It can help reduce stress, improve your mood, and make it easier to fall asleep. The endorphins released during orgasm also act as natural painkillers, which is why some people find that masturbation helps with headaches or, for those who menstruate, period cramps. Increased blood flow to the genitals and the muscle contractions of orgasm may also contribute to pain relief during menstruation.
For men, there’s a notable long-term benefit. A large study tracked by Harvard Health found that men 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 analysis found that men averaging roughly 5 to 7 ejaculations per week were 36% less likely to be diagnosed with prostate cancer before age 70 than men who ejaculated fewer than about twice a week.
What It Doesn’t Cause
A lot of myths persist about masturbation, and none of them hold up to scientific scrutiny. Masturbation does not cause vision loss, hairy palms, mental illness, erectile dysfunction, lowered sex drive, infertility, decreased sperm count, or shrinkage or curvature of the penis. These are old claims with no medical basis.
One common worry is that masturbation lowers testosterone. The reality is more nuanced. A small study found that testosterone levels spike briefly at the moment of ejaculation, then return to baseline within about 10 minutes. After three weeks of complete abstinence, testosterone was measured to be somewhat higher, but research on the long-term hormonal effects of regular masturbation is still limited. For most people, the fluctuations are too small and too short-lived to meaningfully affect energy, muscle mass, or mood.
When It Could Become a Problem
The one scenario where masturbation can genuinely cause issues is when it becomes compulsive. The World Health Organization’s diagnostic manual recognizes compulsive sexual behavior disorder, defined as a persistent pattern of failing to control intense sexual urges that leads to repetitive behavior lasting six months or more and causes real harm to your daily life. The key signs include:
- It takes over your priorities. Sexual behavior becomes a central focus of your life to the point where you neglect your health, responsibilities, or personal care.
- You’ve tried and failed to cut back. You’ve made repeated efforts to reduce the behavior but can’t.
- You keep going despite consequences. Relationship problems, work issues, or health impacts haven’t changed the pattern.
- You get little satisfaction from it. You continue even though it no longer feels pleasurable or rewarding.
An important distinction: having a high sex drive is not the same as having a disorder. If frequent masturbation doesn’t cause distress or interfere with your life, it’s not a clinical problem. The diagnostic criteria specifically note that distress coming entirely from moral judgment or cultural disapproval does not qualify. In other words, feeling guilty because you were taught masturbation is wrong is different from experiencing genuine functional impairment.
Guilt Does More Harm Than the Act
For many people searching this question, the real issue isn’t physical. It’s the shame or guilt they feel afterward. Research on women with high levels of masturbatory guilt found that guilt itself was associated with greater emotional stress and worse psychological outcomes, not the masturbation. Feeling bad about a normal behavior can create a cycle where the guilt causes more distress than the activity ever would on its own.
If you grew up in an environment where masturbation was treated as sinful or dangerous, those feelings can be deeply ingrained. But the medical consensus is clear: the act itself is not harmful. Working through the guilt, whether on your own or with a therapist, tends to be more productive than trying to eliminate a healthy behavior.
Minor Physical Irritation
The only common physical side effect is skin irritation from friction. Vigorous or frequent masturbation without lubrication can cause chafing, redness, or mild swelling. In rare cases, unusual pressure or friction can trigger a temporary skin reaction like hives that resolves on its own within 24 hours. Using lubrication and avoiding an overly aggressive grip are simple fixes. If you notice persistent soreness, giving yourself a day or two of rest is usually all it takes.
