quote Lonelitude :
What is FaceShitting? Is it really practiced anywhere, people?
The initial question was about facesitting, not faceshitting.
Facesitting, also known as kinging or queening, is a sexual practice in which one partner sits on or over the other's face, typically to allow oral-genital or oral-anal contact, or to further ass worship or body worship. It is common for this position to form part of BDSM, involving dominance and submission, though this need not be the case.
Faceshitting is a part of coprophillic play, when someone literally shits on your face. Yes, there are people who like it, and escorts who provide it.
