And nothing against you hairy bears, but I like 'em smooth. I want to feel smooth skin beneath my hands.
I think we draw the line at certain body parts, though, right? Like, if the guy is spreading his cheeks wide, and you see his hole, that would be porn. If the guy is ejaculating, that's porn.
I think I have come up with the deciding factor. If you're looking at some beautiful male form that is displayed in such a way that if your mother were looking over your shoulder, you'd be embarrassed by her seeing you look at it, then for sure it's porn!
