I'm not really sure how being nonbinary is the same as being gay. You realize you are gay because you experience, well, gay shit - homosexual attraction/romance.
You can't experience nonbinary shit, because nonbinary shit doesn't...really...exist. what is a nonbinary experience? I feel like i could get away with calling myself nonbinary because i'm a feminist and i never did masculine shit like play sports. That's rebelling against the binary, yeah?
