Hmmmmm... Where did you get this statistics? Most places I see in non-Asian societies where marrying non-Asian is most possible, Asian men still prefer Asian women since you still get Asian couples the most of time. Even in high schools and colleges, you see Asian kids dating Asian kids. So it is complete nonsense to say Asian men prefer non-Asian women.
One's reality does not equate to one's aspirations, just because a person has GM doesn't mean they wouldn't prefer a Honda. Maybe because their car was handed downed, out of style or they simply got bored of it and even if it isn't necessarily an upgrade, the saying is "the grass is always greener on the other side" and people often want to taste the exotic. I know for a fact in Taiwan, men often claim that their women are "dead fish" in bed.
Asian woman are the easiest for Asian men to get because they tend to be from the same social circles, growing up. Asians tend to congregate together and understand one another culturally and socially better than people from the outside. We form closer ties and relationships from being in the same community, whether it be Chinese School or family friends or neighbors. It is also harder to break out of one's circle and meet new people especially since a lot Asian including ones born abroad tend to have poor communication and networking skills outside their ethnic group, especially the first generation immigrants.
As for the Source Here:
Granted its a small and skewed sample but I haven't found anything else that is better and well there is tendency to be more honest on the internet b/c it is anonymous. Regardless of its those sampling errors, its interesting nonetheless.
