I used to identify in this way, but things have shifted somewhat due to transition.
I have in the past experimented with both men and women, and got precisely nothing from it. As much as I hate to support any of the sh***y you're-just-mentally-ill, maybe-you-have-a-hormone-imbalance, you-must-have-been-molested invalidations that get thrown at asexuality far too often, I believe that for some people, it can depend on how comfortable you are with your own body. I haven't tested this theory in practical terms as I'm still not comfortable enough with mine, but I have been able to conclude that I can sexually respond to women, and can't sexually respond to men (unfortunately). I still have no desire for real sex with a real woman, though, so I suppose that makes me Grey-A on the asexuality spectrum these days.
