Intentionally having my (future) wife or girlfriend impregnated by somebody else than me is NOT on my list and i will NOT promote that. At least not in general.
One of a very few situations in which i could somehow imagine it happen in a planned manner is when my Woman is actually a polyamorous person and in two equal relationships, one with me and the other with the other man. In such a case it would be reasonable for her to have chi!dren with both me and her other man and all of us sharing one and the same house, so neither fathers are deprived of their chi!dren nor the chi!dren of their fathers and we will become one big family. But the only imaginable way for such a scenario to actually work strongly relies on good buddy chemistry between me and the other man involved (in addition to the strong bonds between my Woman and me as well as her and him, respectively).
Another reasonable situation would be me becoming infertile for some reason, so that our wish (my future wife's and mine) for offspring can only be fulfilled with another man's sperm added in. And yes, in such a case i would prefer for her to conceive "the natural way" instead of artificially in a clinic by an unknown donor. And yes, i would prefer the man or men who would be granted the honor of getting her pregnant to be healthy and Black. And i would be raising the chi!d as my own. - But ultimately and of course it would be my wife's decision more than mine.
If impregnation would happen accidentally, well... i am not an advocate for abortion, so i would prefer to keep the chi!d and raise it as ours - in the end s/he will be a product of our love anyway. But again, my wife would have a say in it too, plus perhaps the biological ******* of the chi!d. i think it is best to discuss with all parties involved (me, wife and each of her lovers, even ONSs) and agree beforehand upon what is going to happen in case of unintended pregnancy. As far as i am concerned, i will only accept men as my Woman's sex partners who express not to claim fathership in such a case.
Those are the only three cases that come to mind in which it would be acceptable for me to have or accept her impregnated by another man and deliver the baby. But fortunately most other cases can successfully be avoided in the first place by using more than one method of contraception concurrently - which would also be my advice and choice of lifestyle implementation. jm2ct's worth
