Yeah, that bothers me too. (It's also why I'm uncomfortable with people who identify as pansexual. I don't like being "othered.")
As a pansexual trans guy, I'd like to share my thoughts on this.
The people who identify as pan and say that it means they like men, women, and trans people also make me uncomfortable.
I do NOT think being pan is about liking trans people. Obviously trans men are men and trans women are women, and as such they fall into the categories of men and women. I'd understand if people said "I like men, women, and people who identify in a non-binary way (this is the most inclusive term I could think of, let me know if you have one that works better
When I say I'm pansexual, I mean that how someone identifies (man, woman, bigender, genderqueer, agender, etc.) is not a factor in whether or not I will love them.
I'm sorry that you've had bad experiences with pansexuals, and I hope you know that we're not all like that.
To answer the original question though, I've never dated another trans person. The first and last person I dated was a lesbian, who despite knowing I identified as male when asking me out, refused to respect my identity. I've not been so keen on dating since
I apparently type really slowly, because when I started typing this Nygeel hadn't responded yet
. Sorry for the redundancy I suppose.
