Thinking about it now, i would find it off putting if she had a deep voice, that would be quite important to me.
Also tits, the only tgirl i have found attractive without them is Nancy for some reason, but even then i keep wanting and imagining her to have tits, and found my self liking her without them a little weird.
Apart from the physical side she would have to be fairly feminin in her ways as well, i suppose i would have to make compromises in quite a few areas but I'm not sure where i would begin to fancy her and not fancy her, or begin to see her more as man than tgirl?
I'm even more confused now.
