Absolutely not! In the past, it was common to hear stories that masturbation would make you blind, mad, make the palms of your hands hairy, etc. However, even in those days, masturbation was an extremely common practice. All those beliefs are totally untrue, although strange rumors sometimes persist even today. If all these tales were true, the world would be full of blind, mad men with hairy hands! Masturbation is something that almost every man enjoys, and it's not harmful in any way.
