You're sexually attracted to someone now though, aren't you? Sexual orientation covers gender preference in sexual attraction but it doesn't cover libido, kinks, romantic attraction, single target sexuality, the way you choose to express your sexuality, etc. I'm all for recognizing those things as important parts of sexual identity, but I'd rather that people see sexuality as complex and multidimensional (gender preference, romantic attraction, sexual expression, libido, etc.) than try to add a bunch of new "orientations" that try to describe fluid ideas that go beyond orientation.

So yeah, demisexuality is a thing, but "demisexuality" is a really bad way to explain it.
