born2learn,
I have had all of the very real fears and concerns that you do (and still have one of them).
QuoteI want to make sure that it not a relationship where the person say ok in a relationship then at the last min just back out.
I know in my heart that Amy will not leave me when i'm post op, or at any point inbetween or after. Even though she reassures me and I know she is sincere and honest, it is still a fear of mine that she tells me now that she'll love me no matter what and will leave me when things get different. I need to learn how to trust that and what helped me to get to this point was to say "whatever happens, happens". When Amy and I first started dating she understood very little about F2M's and tried to be very delicate with the situation and has put a lot of effort into learning everything possible about trans people.
As soon as I gave up looking for "the right woman" and trying to make it happen, a couple months later I met the woman I am going to marry. I didn't think this would ever happen for me and thought "how could a [straight] woman ever truely love me?" (I refuse to date lesbians... mainly b/c I'm not a chick! but that's a whole other topic altogether!). It happens man, but I'm a firm believer now that everything happens in its own time and to trust the process, and I know that it is VERY difficult sometimes to not just rush the hell out of it.
QuoteWould a women be disappointed if her guy can't give her a child, what about a man? will he be upset that his girl can't have kid?
This is something that I really struggle with almost daily. Yes I am fairly young to be thinking about kids, but I want more than anything in the world to be dad. I think to some degree (if you and your partner end up wanting children) both you and your SO will be disappointed that you cannot have children with the traditional conception method (this is how it is for us anyways) and it makes me feel like less of a man. But where there's a will there's a way, again, if it's meant to be I believe it will happen.
Keep the faith,
Tino
