I can't speak from experience, but I wanted to comment on your concern about relationships post-op. It's been the experience of (multiple) trans women friends that heterosexual cis men are more attracted *after* surgery. The most common given reason was that they personally didn't think they could sexually function with someone who had a penis instead of a vagina (regardless of gender identification; I do wish to stress that for the majority of these, they were respectful and presented it as an issue with their own sexual function and not because they disrespected or erased the fact that the trans women they were attracted to were still women).
So, while there's probably some individual out there who is flat opposite, I don't think it's something that would be common from what friends have said.
I have to echo the poster who asked, though, why you would even bother with someone who would make a big issue out of you being trans. That would be an instant "Nope" for me.
Also, *hugs and cookies offered*. <3
