What muscles hold your poop. i smell like feces and i'm trying to figure out what's causing this. i went to a proctologist and told me nothing's wrong?

Hmmm.: It is quite a jump from smelling like feces to wondering whether or not you have issues with being able to hold your feces. Proctologists are quite well trained and i suspect that if he says you are normal you are at least not very abnormal and this is not likely the cause of your problem. Have you considered a different organ? Maybe this is your nose / sinus or brain?
