I masturbate 4 to 5 times a week is it harmful am i overdoing it i am 22 year old male?

Sounds fine: Masturbation (regardless of whether it is male masturbation, female masturbation, self masturbation, or mutual masturbation) can have no effect on sexual function, can decrease dysfunction, or can increase dysfunction. The effect depends on issues such as the person(s) views on masturbation and whether or not the masturbation causes physical symptoms (as always, do everything in moderation).
