I think honesty is the best policy. Just be open with her and tell her you would like to try something new. Only you know how your wife will react to this kind of request.
With that said, after a couple of marriages and then a marriage to an open sexually younger female that totally got into the FemDom, IR, cuckolding lifestyle with myself.
As the male you have to love your wife, truly love her, show her, praise her, idolize her, worship her and once you physically, literally and mentality do that 24/7 then you come clean---IMO, better upfront early on in the relationship, here is what I want and here is what I will do for you. But, once you are in it, you are in it. Then you show her 100% worship to her and then, IMO---you crank it up even more when you present your love for wanting to be the cuck and her fucking the superior race! But you have to physically show it, prove it, do it-live it and also do that mentality as well. You have to have the guts to say, "Hunny, I want you with beautiful and precious black men and I want to be your cuck, your sissy, your everything but I want to do this...............................................and so.
They way you want it--------you have to make her want it also. And only you can bring her flowers, candy, massages, oral, worship, extreme showing of your true love of her self and body and then you have to convince her how she will receive all that times 100 when the superior race enters the picture.
She has fetishes and fantasies, but the trick is to pull those out of her, do them and get her to be everything you want, if you are everything she wants. IMO.
