I have. It’s not that big of a deal. I’m into guys, trans guys are guys, I’m good.
I *don’t*, however, top vagina. I’ve tried. It was really awkward and kind of terrifying.
I also haven’t dated anyone — trans or cis — who identified as anything other than male. So no genderqueer trans guys or trans as an identity trans guys. Not necessarily because it’s a deal breaker, but because I tend to not get along with those guys. We look at our gender and histories in such fundamentally different ways that there end up being fights. That’s fine for friends, but way too tiring for a relationship.
