Bulls have more to lose by approaching, use that white privilege and let them know you're interested. My pops told me, don't take pussy, ask for it nicely, you'll be surprised who says yes. Same applies, ask for bbc nicely, you'll be surprised who will indulge you.
Black men in the cubicle era know it's best to appear non-threatening and asexual in mixed company, so we play that role almost to a fault. It's why there's a disconnect, you're seeing our representative most of the time. Catch us alone and show you're interested, you control the social dynamic and forgot, I guess. Compliment us one-on-one if the cologne smells good or you like our haircut. It has to be between the two of you, though; watch the difference.
