Does anyone else masturbate a lot?

I'm not sure what you mean by a lot, but it isn't really an addiction; it is a normal sex drive that we develop when we reach puberty. Our desire for sex is necessary for our species to survive, so it's totally normal and not something to be ashamed of. If you are masturbating so much that you don't have time for anything else (eating, sleeping, school, friends) then it's a problem, but this would be very rare. Just maintain a good balance of activities, and don't feel bad or guilty about being normal
