Hot take: there's no "asexual spectrum," it's actually an "allosexual spectrum"
You see kids making asinine comics (and other things) about how "asexual" includes people who do, actually, experience sexual attraction, just only sometimes, but then end up placing all us non-aces into this single monolith, as if we're somehow always sexually attracted to practically everyone of the genders were attracted to (plus, the constant conflation, with their cake metaphors, of "sexual attraction" with "sexual desire," which they then insist is two different and somehow unrelated things, but whatever, I'm trying to keep this short).
So, since in the real world and not the Acenet, it's extremely rare that one is genuinely sexually attracted to people any more than "sometimes," (and certainly not in this cartoonishly animalistic, "you instantly feel like you want sex with this person" way that the Acenet seems to think sexual attraction works -- that is not at all how it works), it logically follows that the range in which sexual attraction happens is a typical experience, meaning it's "allosexual," not asexual.
It's just basic logic: Asexuality isn't on a spectrum, but us "Allos" are. "Grey ace" and "demisexual" are basically just your typical allosexual kids who haven't realised that they're really just completely average.
And this isn't even considering the implicit LGBT-phobias when "demihetero" kids fancy themselves somehow "qu***" cos they don't want to bang everyone of a dissimilar gender that they see. That's another story for another time.
