Using the definitions people have shared above, pansexual would fit me best. I don't mind using bisexual though, because most people understand it well and I don't see any downside to using it... like, I don't think an androgynous and/or genderqueer person would think "Oh, I have no chance" after hearing me say I'm bi.
My term of choice, the one I preferentially use if given the option, is definitely queer. It doesn't rule anything out, it's easy and fun to say, and it describes, to me, not just a sexuality but an outlook on life that's a little radical, a little "It's all good, baby, yeah." So, I feel it actually gives more of the flavor of who I am without pinning me down.
