I really am surprised to see this on here. I'm definitely seeing what you're seeing. Asian culture does not, and seriously point blank, does not concern itself with sex at all. The closest kids brought up the asian way get of sex ed is to never have it. This is mostly Chinese/Taiwanese.

But, Japanese are a different story. I think the host clubs/18+ red district of their culture/cities is kind of infamous, granted I am not Japanese, but am aware of them. It may be easier to approach a Japanese lady after getting to know her for awhile.

Also in general, the woman, in Asian cultures is very second, very serious second citizen kind of status. Such as in Japan, if there is one seat left on the train and a couple gets on, the man gets the seat. The woman carries all the bags and stands.

For the Chinese/Taiwanese, the western influence has hit much more of the culture so woman have a better status, both socially and culturally.

If I think of anything else I will post back. Also, in the U.S. having a hybrid couple, as I call them informally eg: caucasian partner x asian partner are also rare. So you're on the right road to learn the cultures. If it helps any, you gotta love the culture to love a woman from the culture. I hope this helps!
