I am 21 and have been looking at my penis a lot lately!!! I think its shrinking!!!! Does that actually happen to men my age????? Its a little worrisome to me because if my dick is getting smaller...I surely never will get a woman......What really puzzles me is that i got friends who are 17 and 18 with dicks 4 or 5 inches bigger than me....whats up with that???? Could my lack of size be genetic? Can I live a normal healthy life with a small penis......are there any medical issues I should worry about in the future.....this really sucks..........hahahaha
