Women who identify as straight and who kiss other women for attention, a thrill, or "an experience." Sigh. I used to find them profoundly annoying. Maybe not so much anymore. Yet while I have nothing against a good make out session with Ms. Straighty McStraightyPants, I'm also not really interested in dating her. Or fucking her (or less commonly, being fucked by her). There's always something missing from the equation. Add being a lesbian trans woman into the mix and the situation just gets worse.
I really want to make it clear, I'm speaking here about cisgender straight women and my experiences with many of them across my romantic and sexual history. I recognise many of my trans sisters are, in fact, quite heterosexual. I have not personally had any romantic or sexual experience with other trans women (there have never really been any other trans women, of any sexuality, in my social circles until extremely recently). I'm sexually and romantically interested in women identified persons. And that includes other trans women (assuming I find them attractive for the same reasons I would find any cisgender woman attractive). I'd still want to make sure that any trans woman I was seeing was also not straight.
