Uh it feels good for to realize you have stored all of that crap and held it in fo such a long amount of time, once you let it all go and such of course it will make you feel better. Not only are you not carrying as much waste around, but it also realizes your body from having to hold onto such things that your body doesn't want, thus why you uh "let it out" for once again it's just waste, the bad stuff,supposedly.

I don't understand how enjoying to take a dump has anything to do with someone's sexual orientation, I say you are thinking far too much into it for technically, everybody likes going number 2, for it lets go of the waste, it makes them feel lighter in a way, and their bodies like having to not carry such things around anymore.
