i know a lot of misinformed people tend to complain about bumps on their penis that just end up being hair follicles, but i have one thats on the top of my penis (whereas all my other follicles anywhere on my shaft are on the underside) past the head. It is no bigger than the head of a pin and has no hair coming from it. it doesnt do anything and u can hardly see it when im not erect. Is it just a skin blemish or should i be worried?
