Interesting. Well, first - thanks for being an ally!!
It does seem like trans folks have a pretty rough road in most societies, and predictably that leads to poor mental health outcomes. The statistics about how well a trans person does post-transition has a lot to do with whether they are accepted by their family and friends. (Mental health issues are also common before transition while closeted, or not-yet aware of being trans, which might have biological as well as social / psychological reasons behind it.)
It also makes sense you might not personally know trans women you are attracted to as there are far fewer trans folks compared to cis folks; though, it sounds like you were even able to list a trans woman you do find attractive.
Digging into that more, if there were someone who had the right personality and looked like Jaime Clayton, would being trans be a deal-breaker for pursuing a relationship with that person? I guess I wonder if it’s really being trans that is the problem for you, or if this is just a short-hand for a bunch of other traits that in practice just make you less likely to be attracted.
I ask because at this point it sounds like you would be pretty open to dating trans women who you find attractive (personality and looks wise), but that it is more practical reality that you just aren’t attracted to most trans women (probably for a variety of reasons).
