My wife and I come from Europe. From Switzerland, to be precise. She is Asian and I am white. I don't think the forum reflects reality. It comes across as if every white woman here wants an immigrant. But that's the minority here. For most women, origin doesn't matter at all. Either you're an attractive man or you're not. No matter what skin colour. You can have a huge penis and still not get a woman.
My best mate is black. I was in Thailand with him last year. There it was quite explicit that women preferred white men. I experienced the same thing in South America. In Europe, on the other hand, black men are of course also very popular. I see absolutely no problem there! I'm a white man and can't do anything with white women. I like black women, Asians or Latinas.
