To hullabaloo and musclebutt2
I would like to add an asian's a bit self-critical generalization on it.
First, I can confidently say that some boy-cultures in Asia are very very rough and tough. In my country, if you act like a sissy boy, you are a deat meat in school. Being macho or at least pretend to be is often very important to survivie literally. Consciously or 'subconsciously castereted' could mean the end of the live to many asian guys. (But I absolutely agree that they are heavily 'family-oriented'.)
I think many asian guys have become extra-shy and shrunken in the presence of whites because they tend to think (or are conditioned to) that whites are at the top of the hierarchy of modern society which is true to some extent. And hierarchy is more important in Asian societies than Western societies, I think.
In Asia, the desire of having whiter skin is just enormous, especially among girls. The whitening cosmetic market is multi-billions. And girls and boys seem like to have more western features on their faces when it comes to plastic surgeory.
So, it is maybe natural that asian guys feel less confident when they meet white girls whose characteristics are something many asians aspire. I don't know this comparison fits here but it is like an unemployed and uneducated man would feel inside when he has a date with a highly-educated and high-income girl if I exaggerate. So ironically asian guys are likely to be away from western girls in order to preserve their 'masculinity' because they are intimidating. Being better (including higher, bigger, longer whatever) than others are closely related to masculinity.
And I heard that asians guys who are raised in western world try to overcome or compensate this inferiority pressure by getting higher grades in school. I don't know much about this theory, though.
Lastly, I agree with musclebutt2 that media has been a part of shaping male streotypes of race. Anyway, Bred Fitt and David Beckham are madly sexy in Asia while who was the last widely-recognized sexy Asian guy in Western world? And even black heroes (there are some nowadays) and asian heroes (if any) rarely get a white girl, it seems.
