Someone told me that 1/3 maintain their previous attraction, 1/3 switch, and 1/3 are asexual. I don't know if that is true.
I had wished to be attracted to men, figuring it would be easier to be a gay man than a transwoman, but I never ran into Mr. Right or even Mr. OK. I was always attracted to women. A few months running on the right fuel (estrogen), however, and I no longer had any sexual attraciton to women and began finding men interesting. Many on this site have not switched, but for some reason I have. I haven't ever had sex with a man, but I'm hoping that somewhere along the line I will have the opportunity.
So who knows? I don't know that there is any way to tell how you will react until you take the hormones.
