Same, men and women. That's all there is, two sexes.

I remembered that back then gender and sex meant the same thing, but now they changed gender to mean "masculine" and "feminine" whereas sex is "male" and "female".

Non-binary, pan, 'queer', demisexual, etc I see those terms as a political stance in TQ+. It's haed to meet people who call themselves bisexual, they usually say "pansexual", "queer" or for those who don't want to be associated with trendiness, they may just say "I like what I like" and leave it as that.
