I may be biased, but I suspect that between a woman and a man, both of whom are ideal pasoid transgender men, it is the transgender woman who is more likely to be accepted by a cis man.
Making it clear that I am speaking in terms of "substantial" romantic relationships and not just "easy sex," it is as if the cis man has more flexible standards as long as you give him the right appearance (and don't talk about it too much). Whereas in the case of dealing with transgender men, the cis man will resist, even if the transgender man is a pasoid, taking him as a man like him. I don't know, it is as if there is something about the transgender man that does not quite fit for the cis man.
