I learned where the internal and external rectal sphincters are and what they do (they simply open and close the rectum; although parcopretics' sphincters usually stay shut tight, of course). I learned that the rectum stretches when full of stool, and that's the "urge."
Anyways, about the sphincters: the doctor told me that THEY are the real problem. My brain simply won't allow them to open in public, even if I'm sick with all the poop inside me.
I was wondering if anyone has tried mathman's technique (in the Best Of section) of forcing open the sphincters to get poop out. It seems like it would work well enough, doesn't it?
What are everyone's thoughts?
