I'm a female homosexual and find women attractive regardless of presentation, I'm attracted to biologically female people, not femininity. Some very unfeminine women are fantastically attractive to me. Males really aren't, regardless of how pretty or how feminine. (Still staggered at India Willoughby's recent tweet that Sharron Davies is trans and not a woman because not as pretty as Dylan Mulvaney....ffs.)
Passing.. ? Well I've known a lovely TM complete with full beard. But the hips, the walk, the smile, the eyes, the social skills, the way they interact with people - I see a woman, not a man.
What I wouldn't find at all attractive was the rejection of femalehood and of other women. Too often I find a lot of sexism involved, I've known TM who believe they are escaping a powerless group into a more powerful one and the sexism follows it: women are inferior. And that's phenomenally unattractive in any prospective partner of either sex.
