When I was in Tokyo I was recruited by Soft on Demand (one of the bigger JAV companies) to be in a film. It was going to be for a reverse rape scene where some AV actress would feel me up in the middle of a train and give a handjob/blowjob. I decided not to follow through though. The main reason I got the offer was because one of my friends had been in a couple of AV films and worked in the hostess industry and one of her connections was asking around that they needed a white guy for the scene.
As for the question of Japanese girls in bed a couple pages back...In my experience, most Japanese girls don't do any of the screaming/crying shit that is in JAV. I'd say a substantial portion of Japanese women are super passive and just sort of lay on the bed and don't move. It really depends though. Most Japanese women tend to have hairy snatches, and really the only Japanese women that I slept with who were shaved were girls that I picked up at clubs in Shibuya and Roppongi. In other words, most of those girls had already probably slept with 100 other foreign guys who told them to shave because it's disgusting or whatever.
