There are many sexualities. They are basically fetishes that for some reason are hailed as gender. There are like 72 of them, many are stupid like,
"Attracted to fathers"
"Bisexual but attracted to only one gender."
"Attracted to intelligent people"
I deadass don't care about the 72 genders since 0.00001% of the population actually is one, and those people are already weird af. However, I do think some of those genders are at least valid since they describe something new.
But sexuality is really dumb. Shit like demisexual, need to be emotionally attached to feel sexually attracted, makes no sense. Just keep it to the basic genital and gender cues that you are attracted to. Just because I'm straight doesn't mean I'm attracted every woman. But my preferences aren't my sexuality. Otherwise I'd be milfsexual or some dumb shit.
"Bisexual but only attracted to females."
