My own take on it:
1. Have you given birth to a child before transitioning?No, I haven't. I've always loved children though. So I always thought as a kid I will have children of my own, like everyone. Though I never could imagine giving birth... When I heard about C-section I was like - that's the way to go!
1B, 1C, 1D:If I had had biological children (which I can't imagine), I'm sure those are the things I might have been feeling... I think it might have messed up my mind big time. And made me depressed. And felt 'final' or 'now there's no way out'.
2. Have you given birth to a child during/after transitioning?Nope. And still not medically transitioned... but socially though ages ago.
2B. How did that make you feel? (you can check out 1B, 1C, 1D)I can imagine (no, I CAN'T imagine!) it would make me feel very, very dysphoric... I can't imagine myself being pregnant & breastfeeding for example... When I play with the idea, it makes me wanna die, basically... Like THE WORST thing I could do to myself!!! (And ruin my life completely.)
2C. What lead you to that decision?See above.
2E. Have people questioned your identity because of this? How did that make you feel? Or do you not just care?I have sometimes wondered WHY would any trans man want to go through that!!! But of course I now understand it's because wanting to have biological children, which is perfectly natural.
3. If not, are you going to give birth after transitioning?No. Even the idea of storing eggs feels like...!!!
3B. Again, what are your feelings on it? Do you find it the 'necessary evil' to have biological children? Do you find it just natural? Do you feel joy of the idea?I can imagine it can be any of those things for people who wanna go that route.
4. If you haven't given birth or are not going to, do you still want children? In what way? (adoption, maybe?)Before I always thought I'd adopt. Even as a kid. I've been hugely interested in adoption & adoption stories etc. But as for now we have decided not to have children, mainly because it's such a huge commitment. Plus I like to travel. A lot.
But I've always thought I might do some charity work etc. involving children! I really love children, you know.
4B. Has your gender identity played a role in not wanting/having children? (i.e. not able to, not having found a partner yet, the idea causes dysphoria etc.)Might have, a little. Like I said, as a kid I always imagined having children of my own... But tbh as an adult I've realized that you must put your own life on hold and sacrifice everything for another human being... Who might grow up hating you, for example xD! I don't think children fit well in my lifestyle... Children need a stable environment & available parents which I don't think I can offer... Though I've always been good with children so it's partly a shame I don't get to raise one! But unfortunately I put my own life before everything...

. Which I feel hasn't really even started yet.
Plus at least we can't get accidentally pregnant. (Which is a good thing, of course!)
5. What kind of protection do you use/have used in the past?None, since I'm with a woman. That's one good thing about being a trans man,
