What are the risks of masturbation ?

Worth it: I see you're male. Getting caught -- it's a little embarrassing. If you use a very hard grip / fast action all the time, you may have trouble adjusting to a real-life partner; generally, vary your technique. A teen without privacy who needs speed will need to readjust in a relationship. Rare men get obsessed with erotica ; miss out on the rest of life; your physician can treat this easily enough.

Masturbation: Masturbation is a normal and common part of the human experience. There are no medical or health concerns for this sexual activity. Medicine has nothing to warn you about. All men you know have or do masturbate.
