Pansexual, polysexual, and omnisexual are all microlabels and are all subsets of bisexual. You don’t need more labels than gay, straight, and bi.
Edit: I forgot about asexuals. But I specifically only care about bi subsets. They’re dumb, and you only need bi
Polyamory isn’t a sexuality. It’s a dating preference. Most of these labels do apply to me, and I think they’re redundant.
