I dunno, looking at some of the top videos of certain porn-sites it looks like a lot of people like trannies.
Well, trannies, gay, mature, teens, anal, etc. are relatively normal. What I find amusing, is that according to those charts, a big % of the entire population, is interested in things such as - "scat", "Kim Kardashian" and "hairy anal"

Just how many people want to see hairy assholes?..

I never judge other people's sexual preferences, as long as it does not include violence, but why would, literally, eating shit, be so popular?..

It just can't be true.
