Yeah, mine changed, but how much of it was change, and how much of it was getting out of the closet is something I will never know. I know that in hindsight I wish I’d had experiences as a gay man before I came out as trans, so that I could have experienced positive queer relationships with men. Instead, I only dated women pre transition, and they could always tell that something wasn’t right… My attraction wasn’t quite there…
After much self exploration, I came to understand that I am panromantic, and predominantly heterosexual, however my dating preference is basically “If you’re not openly queer, I’m not interested”.
