Well, i am 15 and i am really worried about having an STD. I have not had sexual intercourse before, but i have masturbated..(a few times) I have these little bumps that look like un-emerged zits on my genitals. The whole thing except the head. Some are just normal un emerged zits ^_^ But the other i haven't a clue. They do not hurt or irritate me. Please help if possible. And none of this "iz crabz OMG" ok? Thanks !
