Masturbation, or rubbing your genitals, is a natural way to learn about your body and what feels sexually satisfying. Lots of guys masturbate, and others don’t. Different religions have different views on masturbation. Masturbation is completely normal, and contrary to any myths you may have heard, it will not cause you to go blind, grow hair on your palms, or cause you to become infertile. Provided that you’re masturbating in a private place, and that you’re not irritating your genitals, masturbation isn’t a medically harmful activity. If you ever feel pain in your genitals while masturbating, it’s a good idea to talk with your health care provider and make sure that everything is okay.
