Maybe a lot of oriental males, going back to the colonial times, are culturally conditioned
to see Western women as beautiful, as something they can't have, as something out of
their league? What do you think?

I'm told that the high end saunas in Macau, patronized by rich Chinese, are 'staffed' in part by statuesque Russians and Poles.
I'm also told, Silverboy would be able to confirm this, that Thai women and men are particularly sensitive to the 'fragrance' of foreigners, Indians, Arabs AND Caucasians. Perhaps female Thai feet are less 'potent' than our own.
