I wasn't insinuating anything about churches and masochism. Japan, for instance, enjoys much BDSM -- especially masochism. The Japanese have a very emotionally repressed outward society that's experienced rapid social change within the past couple of generation . . . it's an unusual situation. But, a lot of their pornography revolves around various control relationships and or humiliation. A lot of weird hypnotism and crazy-sex drug pornography/videogames come out of there.
On a much more seedy level, there's a lot of those said videogames that also deal with rape, especially the rape of virgins. In which, of course, the victim loves the process. I highly suspect this type of fantasy is common in many places. I have seen "rape" pornography (it's fake, no duh) and erotica from the US, among other places -- but it tends to not be nearly as explicit as the kinds of things that show up in Japanese videogames.
Furry erotica has widespread popularity everywhere. It's likely it originated in the US just because the kinds of cartoons and comics that furries are "inspired" by are/were made here. The annual Furry convention, AnthroCon has recently ben being held in my hometown, Philadelphia. Most of the furverts and non-furvert plain 'ol anthro-lovers I've met or talked to are from America.
Man, being an artist with the magical intarweb sets you up to meet a lot of interesting people.
