I always felt it was weird that in the west there's this clear sharp line between porn and not, whereas in Japan things seemed a lot more blurred - it was normal for celebrities to become porn stars and vice versa, for game franchises that started as porn to get a cleaned-up Playstation instalment, for manga artists to release unofficial porn versions of their own work. I remember watching the movie Swordfish and being struck by how much the one incongruous topless scene felt like something you'd see in a Japanese work. So maybe we're seeing some kind of convergence?
