Masturbation is the act of touching or stimulating your own genitals for sexual pleasure. It’s one of the most common sexual behaviors across all age groups and genders, and it’s a normal part of human sexuality. There are no harmful health effects from masturbation itself, and it carries several physical and mental health benefits.
How Your Body Responds
When you masturbate, your body moves through the same sequence of physical changes that occurs during any sexual activity. This is called the sexual response cycle, and it has four phases: desire, arousal, orgasm, and resolution.
During the desire phase, which can last anywhere from a few minutes to several hours, your heart rate increases, breathing speeds up, and muscle tension builds throughout the body. Skin may flush, and nipples can become erect. In the arousal phase, all of these changes intensify. For people with a penis, the testicles may swell and the body begins producing a lubricating fluid. For people with a vulva, blood flow increases to the genitals and natural lubrication occurs.
Orgasm is the shortest phase, a peak of pleasurable muscle contractions and a sudden release of built-up tension. After orgasm, the body gradually returns to its resting state during the resolution phase. Heart rate, breathing, and blood pressure all come back down. Many people feel relaxed or sleepy afterward.
What Happens Hormonally
Orgasm from masturbation triggers a measurable hormonal response. Blood pressure and heart rate spike, and the body releases a surge of prolactin, a hormone associated with feelings of satisfaction and relaxation. Stress hormones like adrenaline and noradrenaline also rise briefly during arousal and orgasm, then drop during resolution. The brain’s reward system releases dopamine throughout the process, which is what makes the experience feel pleasurable.
One common concern is whether masturbation lowers testosterone. Research on healthy adult men found that orgasm from masturbation does not alter testosterone levels. Testosterone stayed the same before and after orgasm in controlled studies.
Physical and Mental Health Benefits
Masturbation offers several well-documented benefits. It can improve sleep, likely because of the prolactin release and the drop in muscle tension that follows orgasm. One large study also suggested that men who ejaculate frequently may have a lower risk of prostate cancer, possibly because regular ejaculation prevents the buildup of potentially harmful substances in the prostate gland.
On the mental health side, sexual arousal and orgasm are associated with stress regulation and improved mood. Research on women found that masturbation served as a reliable coping and self-care strategy, producing positive emotional states like happiness and relaxation. Different types of stimulation may produce slightly different effects. Clitoral stimulation, for instance, tends to be associated with stress relief and mood enhancement, while vaginal stimulation is more commonly linked to a calming, relaxing effect.
How Common It Is
Masturbation is extremely common at every stage of life. In a nationally representative survey of 1,500 U.S. women aged 40 to 65, the majority reported masturbating within the past year. Rates ranged from about 56% among postmenopausal women to 73% among perimenopausal women. Rates among younger adults and among men tend to be even higher. Adolescent masturbation is so common that clinical guidelines specifically note it should not be treated as a sign of any disorder, even when it causes some embarrassment.
Despite how widespread it is, many people grow up receiving mixed messages. A study of 72 college students found that most learned about masturbation through media and peers rather than parents or teachers. The researchers identified a common internal tension: people recognized masturbation as pleasurable but also absorbed cultural stigma around it. Women were more likely than men to still be working through that contradiction, while men more readily acknowledged its role in healthy sexual development.
Common Myths
Masturbation does not cause blindness, hair loss, erectile dysfunction, or infertility. None of these claims have any scientific support, and they have been debunked repeatedly. Premature hair loss, for example, is driven by genetics. The myth that masturbation drains the body of vital energy or nutrients has no biological basis. These ideas trace back to anti-masturbation campaigns from previous centuries. John Harvey Kellogg, the cereal inventor, marketed corn flakes in the 1890s partly as a way to curb sexual desire, but there was never any evidence behind his claims.
Potential Physical Irritation
The main physical risk from masturbation is simple friction. Rubbing the skin too vigorously or for too long without enough lubrication can cause tenderness, redness, swelling, or in more severe cases, a burning sensation or blisters. This is especially common on the penis but can happen anywhere.
Using a water-based lubricant is the easiest way to prevent friction irritation. If soreness does develop, giving the skin time to fully heal before resuming is important, since continuing can make things worse. Wearing loose, breathable clothing and keeping the area clean with warm water also helps recovery. A gentle moisturizer can soothe minor irritation.
When It Becomes a Concern
Masturbation itself is not harmful, but in rare cases, the behavior around it can become problematic. The World Health Organization recognizes a condition called compulsive sexual behavior disorder, which applies when someone experiences a persistent pattern of being unable to control sexual urges over six months or more, and that pattern causes significant distress or impairment in their daily life.
The key markers include: sexual behavior becoming the central focus of someone’s life to the point of neglecting health, relationships, or responsibilities; repeated unsuccessful attempts to reduce the behavior; continuing despite clear negative consequences; or continuing even when the behavior no longer brings satisfaction. Importantly, simply having a high sex drive or masturbating frequently does not qualify. The diagnosis requires genuine loss of control plus real harm to your functioning. Feeling guilty about masturbation because of moral or religious beliefs, without any other impairment, is also not the same thing as having a disorder.
