I think newlifephilippines is correct. Regardless if your Asian or white if you act like player in Asia and let say break a girls heart. She will remember and avoid those guys or hold bitterness. Since your a foreigner anyway....it makes it harder for the next guy looking for something legit.
I'm Asian myself..so I can relate with the discrimination that Asian men deal with in the dating market. I mean there probably is more reason for Asian guys to go overseas than white guys BUT saying that you say that you were an ex-model and tall. I met tall decent looking Asian guys in the states...they had no trouble dating local American girls..but they did it by approaching white or whatever type of girls . So even in the states it's possible although I think for Asian guys we have to work harder.
If what your saying is true about Thai women looking for the better deal or cheating on their husband...and Thai men being left out. I mean what's the situation in THailand ? There still guys out there going to Thailand looking for wives and legit girls but according to you Thai women are not that great.
I did modeling for an Asian country, not in America. I do not have the rugged masculine American look, rather, more of the Korean/Japanese bishonen look that people in Asia dig. So I do get dates in America, but it's nothing like the quality and quantity I get in Asia, that's for sure. The truth about American girls are that the majority of them want nothing to do with ethnic minority men. There is a study done on Okcupid that showed that the majority of white girls AND Asian American girls only want to date white guys. Of course there are still some girls who are willing, but the effort it takes to wade through all the "romantically racist" women is simply not worth it. Note I am talking about hook-ups and not long-term relationships. Finding someone to be in a long-term relationship in America is not hard, but getting consistent high quality hook-up in America as an Asian guy is extremely difficult without some kind of fame. The difference between America and Asia for Asian guys is that being in America is like playing the game with handicap on hard mode. In Asia, it's game on "normal" mode. For whites, some Asian countries would be "easy" mode.
I've heard that normal Korean and Japanese women tend to prefer their own men, but the same cannot be said for women in other Asian countries (although Hong Kong is also kind of like that too). In less nationalistic places such as China, Taiwan and the Philippines, most women I've talked to have at least some attraction curiosity towardwhite men, but they don't date them because of fear of language barrier and lack or opportunity to meet one.
As far as age gap is concerned, unless the woman is a gold-digger, most women in North-east Asia strongly prefer to date men close to their age. 10 years is too big of an age-gap in those places. But women in Southeast Asia are more lenient when it comes to age, and 10 years is nothing.
