I conceded back as a teenager I'd likely never have kids of my own, and took the usual steps to prevent it (condoms, they work.) It turns out the first woman I married was more hostile about having kids that I was, no compatibility problem there, we were a happy enough pair of DINKs. The woman I am dating(may marry) has a single kid, that's fine by me. Truth be told I'm already aging too far to be a good parent longevity wise, my partner isn't motivated to adopt, I am not preserving DNA. I acknowledge my dad died before I hit twenty, it seems like a bad precedent to attempt kids too late.
edit added: I am VERY hopeful for future generations of MtF to have functional uterine implants. I'd be thrilled to have a kid of my own, science just isn't there yet.
