Something which doesn't get enough note around here: for women in their forties and fifties in America it is entirely possible that they were never approached by black men when they were younger. Many of us didnt even have black people around us until we got into the workforce. Things were different 30-40 years ago - women in general were far less likely to ask men out, they waited to be asked. And black men were less likely 30 years ago to ask a white woman out. So some of those women married the guy who asked, not out of any real preference, but because that's who asked them out, that's who they got to know and love. It's not that they wouldn't have dated a black guy, they just weren't asked. You guys in your 20s and 30s are way more likely to ask out a white woman than black men decades ago, because society has changed. And women who are older and more confident in themselves are more likely than a younger woman to ask a guy out. I still find that difficult. I've done it, but when I was being raised, ladies didnt ask men out - it was considered déclassé. There was quite a lot of press on how guys didn't like it back in the 70s & even the 80s.
I dated a black guy in my early twenties, and it created a stir among some of my friends at the time. I dated black men in my forties and fifties and nobody really gave a damn. But to this day, black men often tell me I 'don't look' like I would date interracially, whatever the hell that means.
