I had unprotected sex with a girl and the day after a red bump apeared, it dosnt ich or hurt, not even to the touch. It's just now going away after about two weeks, what could that be? When the bump showed up I became very paranoid and started to inspect my penis. I noticed hundreds of tiny bumps not even raised, and a few raised bumps. I tried to pop the big bumps and a white stringy substance came out, none of these bumps ich or hurt, not to the touch. It dosnt burn to pee or anything. Zero pain. I have only had sex one time, she took my virginity. I'm only 17 and I'm so scared. Could I have a STD? I don't know what to do. Help please
