Where are the Asian men and Black women couples?

Croatia.

I never really thought about it but if I had to guess I’d say most Asian men are probably more comfortable dating Asian women. Outside that comfort zone they would most likely date a White woman. The same can probably be said for Black women. Then again it could have to do with where you live for Example: I live in the Caribbean and Indian men date Black/ African women all the time due to our mixed cultural background.
So I guess it all depends on what kind of Asian men your referring to where you live and what cultural norms dictate when it comes to interracial relationships.
