I don't want to have kids, but if my partner really really wants them and I love them a lot I would consider it.
I might feel too dysphoric to have them myself, but I am 100% willing to consider adoption. I'm probably 50% or less likely to consider holding the kids inside of me, even if I love my partner a lot a lot. That partner would have to be super special to me.
If we were in a 2+ relationship, like poly, I might ask one of the other partners (if that is possible) to carry the children instead
