There does seem to be some weird dynamics. Black women, according to research, some of which is conducted by dating apps, find that they are lowest on anyone's desirability index. I do see far more black men with white wives/partners than the reverse, and I'll bet your interracial marriage friends aren't much attracted to black women. Not accusing them of racism, but suggesting there *could* be a level of fetishism there. I found the black guy ---> white woman fetish stronger in the US than in Canada, but I was over forty when I moved here and also we're so diverse it's easier to meet people of other cultures & races you might find yourself attracted to. What I did find when I moved here is how fetishized I was by Indian & Middle Eastern guys. Like they almost *exclusively* were interested in me. A friend has told me a white partner is a sign you've 'made it' in Canada, but he's a conservative so I'm not sure how true that is....his judgement is up for debate apart from being a conservative.

I do know black guys are often fetishized by both straight women and gay men for the myth of the BBD - the Big Black Dick. Explored it a little in a Medium article back I wrote on the racist African penis enlargement spam I was getting. It was racist, misogynist, offensive, and well--funny as fuck :)
