They've all still got their stupid Asian princess dreams, that's why.
I'm increasingly of the opinion that Western men select shitty partners in Asia due to a lack of understanding about the people.
Opposites also attract and that is partially explained to the fact that black man are often more than willing to sexually pleasure the ugliest white trog imaginable. Likewise, white guys would be happy to just bang anything that's not white, half of the time.
I wouldn't say all Chinese women are bad, but Western guys have a bad habit of selecting the worst kinds imaginable.
