Nope, the Japanese are the second biggest porn producers in the world next to the USA, and they also produce the weirdest fucking shit. Scat films, bukakke, gangbangs, toys, bdsm, and weird things like naked girls playing baseball, and gymnastics.
There is a lot of pervy stuff that they do, and all sorts of sub-genres. Futanari for instance, dickgirls fucking other girls and guys. Ughhh...
News casting bukakke, and I saw a film once of like three hundred couples fucking at once.
Weird, really weird. And don't even get me started on the hentai, its a sub-genre all to itself.
