Or she's just not turned on. lol.
I've dated a trans man (identified as a dude, asigned female at birth). It sucked. Mostly because he acted and looked like a man and I'm not into men sexually. But hey, at least I gave it a shot.
I've also dated a trans woman. It was nice. She was nice. My only complaint is that the sex was practically non existent.
I think trans women are women and trans men are men. My libido says so. Plus ship of Theseus. If it looks like a duck, quacks like a duck then it's a duck. I think the logical fallacy here is that people assume identity is persistent because let's face it, human identities are persistent. Our stream of consciousness feels like one continuous stream. But I guess where we go wrong is that we assume that they were born a boy/girl, just like us but they weren't. They were born either neurologically female in a male body or vice versa. Which means their perception of reality follows that neurological wiring, not their exterior. So they never really used to be a boy (for mtf) /girl (for ftm). But we assume it to be so because their sex characteristics when they were young tell us so and we (correctly) assume that birth gender identity is concrete and set for life. This likely wouldn't be a problem if we just took a child's word for it when they told us their gender and let them be who they want to be instead of railroading them according to the presence or absence of a 1inch penis at birth.
I'm a cis girl but I experienced gender policing too. I was a tomboy growing up, I loved to play in the dirt, I loved violent video games. But whenever my parents caught me playing counter strike or swords with male friends, they would punish me. I would get the wooden spoon until I acted like a proper lady. It sucked. The thing is, that was just activities. I can't imagine what it would be like for a a trans person who is forced against their will to not only do activities they don't like but to pretend to be a gender which they are not and forced to go through a puberty which turns them into their (internal) opposite sex. I think we should cut them some slack. Not necessarily date them, I mean if they look like a trainwreck then ofc not.... but if they look, act, talk like the real deal then maybe give them the benefit of the doubt?
