The majority of straight men probably do reject women with a trans history, based on my own experience dating men, the majority of men I dated rejected me when I disclosed my history.
I'm post-op since 1985, living mostly stealth, I was dating my boyfriend for nearly 18 months before I revealed my history, I only disclosed because he proposed engagement & marriage, his reaction was shock & surprise, it was a differcult decision, we worked through it, he accepted me, he never know me as a guy, he only knew me and accepted me as a woman, he is now my husband, everybody's experience and situation is different, being post-op and only ever knowing me and experience me as a woman, was probably a big factor in accepting me. If I disclosed early in the relationship things might have turned out different.
