So the elephant in the room here that no one is discussing: How do you feel about abortion? I very strongly support a woman's right to choose, and her choice is none of my damn business. But I am personally opposed. Perhaps that is based on my privilege, ability to afford another kid. But if you are in the life-style and she is still fertile, she can get pregnant even if on birth control. Unlikely, but possible. What would you do in that case? I think it irresponsible not to have these discussions before hand. So if it came to that in my case, I would hope I would man up and raise the baby.
Men have been raising other mens children throughout millennia - the only difference here is with the race. And while there are differences in the races, racism is a 100% learned, societal construct. You don't have to tell people anything, But if you do, or the *******, it is easily explainable in today's world. "We wanted a baby, or another baby, but I had health problems. We considered the adoption route, but decided to go the fertility clinic route. There was some mix-up, they offered us a nice settlement - but we wouldn't hear of it. We love all our children and feel blessed to have a healthy ...."
Obviously, this is different than choosing to go down this path - but not that different. Sex is the ******* of gravity that bonds a marriage together. Best Friend, Soulmate, Provider, Caretaker when sick, .... are all held together by the bond of marital sex. When a man becomes a cuck, that bond is ripped apart - like splitting an atom. No matter how much you discuss and plan for it, nothing can prepare you for that first time seeing another man replace you. As a man, you are forever changed. Some marriages do not survive it, but the best ones thrive. If you love her more than anything such that you would risk your life to save hers (not risking it because it is what society expects, but truly because you love her so much), why wouldn't you raise her baby? If your just in it for the kink, absolutely not. But if you are in it because you love her more than anything in the world and you simply cannot pleasure her the way other men can and once you see that, you could never dream of withholding that from her - it is an easy decision.
