So, here is the deal. I have these red spots on the head of my penis, not all over, just kind of in the center from base of the head and they go up a bit. They go away, and come back after being sexually active (ive never had sex, only received oral, and messed around that way) or masturbating. They are sensitive to touch, but don't bother me otherwise throughout the day. Im a little concerned... so if u have any ideas, please let me know, asap.
