I do not see any reason why not.
Personally I support polygamy. We have talked about, fantasized about marrying a black man. Hubby spent the first few years of our marriage as a sissy and we dated white men together back then. Raising a family ended his dressing, but sexually he remained more submissive and more fem then masculine in bed. For our 12 years black only, we date bisexual black men who want both of us.
