In my youth, I dated mostly White women. The only exceptions were two Middle Eastern women (surprisingly, both Muslims and both one-night stands) and a sporadic fling with a Korean divorcee (8 years older than I was). And, of course, my wife is White.
However, somewhere along the line (maybe 15 years ago), my switch got flipped. I am just not very attracted to White women anymore. I think it stems from a combination of disliking their general attitude and seeing how poorly White women age. I keep in touch with some old GFs via Facebook. In all but one case, they really let themselves go. Some of them so much so that its painful to look at them.
In contrast, the Asian women I encounter frequently pass for 10, 15, even 20 years younger than they really are. And, for the most part, they don't have that American feminist entitlement. What's not to love?
