and Polish man are not very "prestigious catch" to put it lightly
Well, if every Polish man was as attractive as you, Poland would be no longer on the map because all the women would just get away from there.
The reason why there are not so many white men with black women is that black women are not very attractive on average, even if you spot a good looking one the chance that she isn't a big mouth with the mood swing is pretty small. Those are surely not types of women that Polish men look after, I myslef know only one Polish guy with the black chick but there surely are more. Getting a black girlfriend is an easy task in my opinion but getting an attractive one is not, there are not many of them so the competition is high.
