So, has the title says, when I pull my foreskin all the way back it has like a bump. It is not itchy and it isn't visible if the penis is with the foreskin in its normal position. It isn't truly a bump, it doesn't hurt, doesn't itch, but I'm kind of scared of what it might be. I can't describe it any other way, to be honest, it seems like a "mountain" in the foreskin.
