I am 15 years old. I have this pimple shaped thing near the toppish part of the stem of my penis. I have never had sex before, however I do masterbate on a daily basis.When I first saw it, I panicked and popped the "pimple" the white stuff that normally comes out from a popped pimple came out. Do I have genital warts? Or is it just a pimple, if it is just a pimple, how do I get rid of it?
