When people masturbate, they touch or rub their own genitals because they like the way it feels. This won’t stunt their growth (keep them from getting taller) or cause any health problems.

You might hear other rumors about masturbation — that it can cause diseases, blindness, or mental problems; affect periods; or stop you from having kids someday. But these things aren't true.

People often think of masturbation as a private topic. They may feel embarrassed to ask or even wonder about it. When something feels too awkward to talk or ask about, people might believe things about it that aren't correct.

If you have medical questions about masturbation, talk with your doctor. Chances are lots of other patients have asked them the same questions before.
