Are dark nipples and a dark v@gin@ a turn off to white men?

Some guy just asked a question 'why do black girls have dark p@*&!#? do they not wash down there?" is that really what white guys think? because my bf is white and i want to have sx with him but now i feel self conscious , i have dark skin so im naturally dark down there (my outer lips are very dark, almost black and my inner lips are pink ) would this be a turn off? :(
