Re: Bump on bottom of penis?
It may just be the early sign of an acne. Sometimes we get pimples on various body parts that just start out as a small red bump. And, sometimes they just clear up on their own without turning into a full blown zit. Because of its location, you're probably a lot more concerned about it than you would be if it were anywhere else. Since it's obviously not an STD, I'd try not to worry too much about it. Give it several days. I bet it clears up. Hope this helps.
