48/m/Oklahoma - Question.

I see a lot of same sex couples looking for sperm donors to have a child. Being a male wanting a child myself was wondering if any of those couples would be willing to both carry a child, one for them and one for potential father?

My assumption would be they would say "NO". Why would they since there are so many donors out there willing to give without anything in return. Also, if they are wanting a child I would think it would be that much harder to give a child up. That is my thoughts. Am I right or wrong? Other reasons besides these.
