ITT: disguisting body stories

I have these really painful sores all around my butthole. They hurt a ton most of the times I wipe.

No, I am not planning to do anything about it, as long as they don't start leaking pus or the pain becomes unbearable.

So, tell us about the interesting (in a lovecraftian way) things about your body.

P.S. I know mine isn't really disguisting, I just wanna hear 'em from you.
