No. Although there are many myths about the “risks” of masturbation, it is safe. Masturbation isn’t physically or emotionally harmful in any way. Masturbation is the ultimate form of safer sex — there’s no risk of pregnancy or infection. It’s possible for frequent masturbation to cause skin irritation, but using plenty of lubricant can prevent this from happening.

Some people masturbate more than once a day, some people masturbate once in a while, and some people never masturbate — all are completely normal. Learn more about masturbation.
