I have always feel there is something extra in front my anus, especially when i go for big. after look in the mirror I notice there is extra skin fold in front my anus, how to describe, hm... like a little door closed/cover my anus which is so not normal, and I cant find any name to call it. so far I am embarrassed to talk about it with doctor or anyone. please if anyone can give me some options? was is bad? have you had any personal experience or know someone had similar condition?
