What is this bag of skin above my anus? Looks like a round red bean. It doesn't usually hurt on everyday life (maybe it does when I shit), doesn't hurt if I touch it, but I just realized that it hurts like an open sore if I touch it from the side where it touches the anus. The only reason I'm worrying about it is because I want to start simulating my prostate. Idk if it's the cause of it but two years ago I had my anus bleed and hurt for a week because I was spending the entire day sitting on the computer, but the procto didn't find anything wrong.
