This is a bit embarrassing, so don't laugh or make jokes please.
I have a red mark on the tip of my penis (on the head). It doesn't hurt, but it doesn't look normal. I'm only young. Does anybody know of something like this?
What does it look like? Does it itch? How long has it been there? Does it have any fluid in it? Does it hurt? How old are you? When was the last time you had sex? How many people have you had sex with?
