I think there's a legit Satanic angle to it too (the perversion of the normal hetero sex act). Like, think about the whole idea of the "cumshot" and cumming on a girl's face. Where did that idea come from? I never would have thought to do that in a million years. Why would I want to defile my girlfriend like that? Cuz that's what it is. Its defilement. We are made in the image of God and the female face is arguably the most beautiful thing God ever made. Of course Satan/demons would want to defile that, and piss God off all the more by teaching millions of people to do it themselves, which millions will and do because the bulk of the human race is monkey see, monkey do. I'm certain it's demonic in origin.
