Many years ago, I went to a club and was almost immediately attracted to this guy. I mean just looking at him made me wet. lol Turns out the "he" was a "she." Did learning that make me feel differently? Yes. I didn't want girlie bits on a man.
After a few more years, I was introduced to an amaphradite and my heart went out to "her." By all outwardly appearances she was a "he." Unfortunately, emotionally, she was a woman, who was forced by nature's slip to lead the life of a man. Whilst visiting a club, she wouldn't even pee because she'd have to use the men's washroom. She ended up killing herself.
I've had transgender friends, some of whom, became what they wanted via surgery. It didn't change the way I felt about them, because they always were, who they were, psychologically, all they did was change their physicalities to match.
If I were in a relationship with a man, who was once a woman, why would I end the relationship? He was always a he, in his mind - in his heart and to me.
