I wish I had some statistics. I'm not sure why, but straight relationships between two trans persons seem not extremely common. I see lots of gay / lesbian relationships between trans people. I see some gay / lesbian relationships between cis and trans people, and a fair number of straight relationships between cis and trans people. I'm not sure if that's really the case, it's just what I've noticed.

Mostly what I see around trans men and women is a lot of loneliness.

It's a little weird, being able to show a picture of him to people, and have them find it totally unremarkable that we are together. (We just look like a straight cis couple.)
