I'ma say this, from the women I've talked to they admit they don't like "nice guys". They rather a.ssertive, aggressive dudes because it keeps them on their toes. There's a risk & challenge dating them.....and they like that challenge.
This applies to most women, not just black ones. No bi*ch wants a boring pus*y for a man, if they do settle down with one it's just for the financial security.
