in film era american used to have great porns, with very good storylines and acting skills
yes, different culture, different way of live
yeah, JAV are more rich in fetishes, foreplay, genres & themes
sure, there are always market for innocent persona in JAV, they always welcome passive girls, which I hate, but many other peoples love them
the ugly, skinny, fat, midget, weirdo with small & limp dick guys still can get a job in AV, while for the female as long they are a bit cute and have innocent persona they can be a star too, even they are terrible in sucking and fucking, they only need to lay on their back, spread their legs and make noisy moans
