8 XXX : Cuckold

i have an honest question: why are most cuckolds looking for Black guys? <- black guy here.
Color contrast
Perhaps the risk of a black baby, and not being able to hide it? Or the perception most pimps are black? Or the folklore about black being bigger... Once you go black, etc Or in some circles, interracial couples are still not the norm so it is more taboo. I think it is many different things for different couples.
