about three weeks ago i noticed what looked like an ingrown hair on the underside of the shaft of my penis. i didn't do anything to remove it however and now it is an unsightly red bump that won't go away. ive taken a sterilized pin to it like you would an ingrown hair, but only blood came out and there was no change. any help on how to get rid of it? i'm 16 and the last thing i want is a girl freaking out because of it.
