This seems to be a very natural and healthy development. In my opinion.Same as my wife. She’s only interested in brown or black men now. It wasn’t a conscious choice, it’s just that white men don’t turn her on anymore really. I’ve watched attractive white men hit on her and she politely turns them away. There is a guy at her work who wants her and she strings him along for favors but we laugh about it at home. It doesn’t stem from contempt though, she’s just traveled that road enough in her words. Black men turn her on.
