I hate to give DR an unhelpful answer, but to post a minority viewpoint...
I really have no special attraction to AA women at all. The AA (and mixed race) women I've been attracted to and been intimate with I've been attracted to because they have the basic qualities that I find attractive in any woman of any race/ethnicity: good looks (though if anyone here has seen the women I've dated outside the hobby they'll realize that's a somewhat low bar), educated to at least the HS grad or GED level (bonus points for some college to degree holder), well spoken (i.e., writes and speaks using correct, standard English), interesting conversationalist (bonus points for being a geek or at least geeky), and has with me that elusive quality we call "chemistry".
Just call me "Mr. Equal Opportunity".
Cheers,
