Certainly it takes more than a complementary shared enjoyment of interracial sex but I do think it's possible for a couple with a complementary sexuality to be able to strike up a chemistry and intimacy on other grounds too.
Maybe it's different for the woman but as a cuck I'm attracted to white women who like big black men just as many men are attracted to blondes, brunettes etc. It may not be the norm but to me it's real and an intrinsic part of who I am.
I have met up with a woman who was 'black cock only' but wanted a white cuck, and unfortunately the chemistry wasn't there between us. But it does show that there are women out there who will give such a relationship a go.
Likewise, I became very close to another white female who was passionate about black men and wanted a black baby, but again, despite an intellectual and sexual intimacy, the fact that she wanted the baby not to know its ******* was something I couldn't agree to.
But still believe it's possible for a white male to find a white female partner who wants an interracial cuckold relationship.
