Do you know any black couples that choose to enjoy themselves the way you and your partners do? I never hear of any and I’ve never seen any, I’m starting to think maybe I’m the odd ball out for having an interest in it

Of course there are. Kink doesn’t just skip over entire races, though it may be perceived differently across different cultures. There’s tons of people and blogs on here run by black couples/individuals who are interested in kink and are engaging with it!
