Interesting perspective. It is of course a fine line between "less egotistical" and "submissive." In my experience (lived in Asia, dated Asians all over the world) many Asian women are not submissive as much as less repressed. The women I dated over there were definitely NOT submitting to anything. They simply "seemed" to enjoy themselves and express themselves more freely. Of course that is a statistically irrelevant sample, but I think there are enough men who feel this way to suggest a kernel of truth. I used to think of it in terms that western women (actually American women) view sex as a power struggle that must be won or fought to a draw, while Asians (and frankly, most Europeans, Aussies and even Canadians) view it as pleasurable play between consenting adults. IT may not be true, but it is the way to bet.
Also, an noboby seems to point this out, Asiam women dress better, are thinner and look after thier apperance much much more than American women. Ride the subway in New York or Boston, or walk the streets of San Francisco or Philly. It is pretty clear. Is this exploitation? You decide. But I am guessing that most women prefer a man who takes care of himself, dresses well and looks good. So perhaps we are all exploiting each other.
In any event. I can't get over the feeling that American women are pissed that another group of women is stealing their men by better looking and better in bed. I would point out the incredibly education many of them posess, but that is not what we are really talking about is it?
For what it is worth, my wife is Asian, she has an MBA from an Ivy league school, and is definitely not submissive in any way. Oh, and she is a fox.
