Well, don't know if this applies but; I use to consider myself bi or at the very least pansexual before HRT. After HRT, I can't possibly imagine a relationship with a man, any sort of intimate relationship with a man physically sickens me. Not saying I hate men... just not into them romantically, sexually, emotionally, mentally, etc.
Having said that, I am not above being able to appreciate an attractive man, simply out of aesthetic appreciation. But as far as orientation goes, I'm 100% girls only. Interesting development however ~ I love women now for more reasons than just the basic "male" reason. Not that back then I was motivated by libido only, but it was mostly dick-thinking. Now, its an overall connection more than anything, I have an appreciation for their small details, for the color of their hair or the way they laugh, or simply the way they speak... its like my attraction to woman has become less sexualized and more romanticized, which I love because it makes the attraction feel sooo... (cliche but...) "Dreamy"... Not with every girl of course, just the ones who captivate me. I'm happily married anyway so it doesn't matter, but even with my wife, I'm more intimate, I'm more emotionally connected, interested in hearing her voice or feeling her energy. Its difficult to explain.
Granted; I find the idea of a straight couple to be cute, I like the idea of a guy falling for me... but I can't imagine ever having the patience or attraction to them so its more of just a girly "aww that's beautiful" kind of reaction more than anything.
So i guess I'm the opposite of you in the sense that I'm girl crazy instead of guy crazy after hormones. where before I was bi/curious/pansexual
