cis, enby, trans, whatever, you're still you. And from what I understand from the terms, genderfluid would be accurate because it means that your gender isn't solid, it is fluid, it changes depending on the day and how you feel. As for lesbians liking demigirls, yeah, that would depend on the person. Personally, maybe. And I've never really had a crush either, don't ask how I know I'm gay tho.
