The act of living under a "fecal dom" who allows or disallow personal bowel movements. The (poly) meaning the "fecal dom" is overseeing many 2-7 "fecal subs" this of course ads to the degradation as you are only one of many "fecal subs" one of the main rules is you can only gain permission of bowel autonomy (for a set period of time) if the "fecal sub" asks in person over the phone or by mail is not permitted.
"Poly-erotic fecal subordination has made my daily life more structured and more erotic!"
"Wow, that's awesome!"
