For a while I oscillated between identifying as gay or bi, or maybe pan or omni, because I found pretty much all the genders to be (sometimes) attractive. What I didn't know what that I was mistaking aesthetic attraction for sexual attraction... *sigh* Nothing actually ever felt 'right', though.
Then I discovered asexuality sometime in senior year of high school, and it was great, because I finally could look at something and go "yes, this is me, I identify with all of this!". Never looked back.
