After many many years of dealing with American women, I've hit an interesting point. go Asian, or Russian, even European (except British, Italian, and French women) and you can't go wrong. I'd take a foreign-born Russian or Latina woman any day.
I've lost ALL sexual interest in them, in fact I just about puke walking down the sidewalk on any day, seeing all those shitty, rude, mean, snotty American women. But show me an American chick and I basically couldn't care less. I suppose from an intellectual viewpoint I can see the beauty, but it's not any more attractive to me than...let's say...admiring a beautiful horse or a well-groomed cat. They say that sex is 90% mental...well, my mind has rejected American women completely. They are much nicer and normally MUCH SMARTER than most American women - plus they don't watch tv all day - they go to the library or perform outside activities.
Yes, when Commodore Perry first sailed into Tokyo Bay Japanese women were very submissive, because Japanese society was highly ordered and because there were very stiff penalties, including potential violence, for women that violated the social norm as a submissive woman.
You can find a Russian woman who is totally submissive and there are Filipina's who are pushy type A women.
Whatever grain of truth existed in the national stereotypes has changed, because the countries where most of the mail order brides today come from have under gone enormous social, political, and economic change in the last twenty-five years.
If you are thinking about persuing foreign girls for marriage there are several issues that you should consider.
The first of course is what area of the world you are considering pursing a bride from?
