I do believe that when a white woman fucks a hung black man she will forever crave it and he will forever crave them. Very difficult for a black woman to compete with a white woman once he has tasted the nectar of lilly white pussy.
I agree with you, on the myth that a black man will "always" impregnate a white woman. Where some people come up with those theories is always a mystery to me! And any cum that any man ejaculates inside of her can make her pg, as I found out the fact that a man's sperm can live inside of her for 2 days! With the millions usually squirted in her during a typical fuck session, and if close enough to her most fertile days (middle of her period), there is a higher chance of making a baby for them!
