I love someone who is also trans (MTF). I had wondered, previously, if it would be an issue at all. But it really isn't any different from dating a cisgender woman, for the most part. Trans stuff kind of is double edged. It has the potential to start fights that wouldn't happen otherwise, but we also understand that part of each other's lives too.
Even if I liked guys though, I could never date a trans man, ever. It would bring all the issues too close to home and...just, never. I'd be with a cis guy if I was to be with a guy at all.
