I made sure to browse threw alot of posts to see if my question was already answered but I didnt find it.Under and on top of the "head" of my penis has small white bumps i guess you could call them..they are different shapes and sizes,but all of them are pretty small..and are mostly focused around the left side of the penis head.I never noticed these until I started masturbating..They cant be popped and they dont go away.Ive never had any sort of sex before so it cant be an STD.The only thing I can think of is it may be some sort of scar tissue from me masturbating to hard. any comments or ideas will help its been stressin me out...
