It's called biloveual.
You can say the terms demiloveual panloveual omniloveual and polyloveual mean something different from biloveual, but they really don't.
The problem here is there are people who deny the idea of a gender binary. There are two genders, and only two, and the word gender means the same as the word love. (save for the act of love)
Anything to the contray is splitting hairs and making up neologisms to sound origional.
except they do. not every conforms to your ideas of gender. sorry.
think of it this way: if the idea of a gender binary is 100% correct, when the idea of somebody not being cisgendered/heteroloveual isn't surprising, and the "edginess" of these labels fades, we'll discover whether people are still claiming to be panloveual, omniloveual, demiloveual, polyloveual, etc. if they are still doing so, then it's a legitimate thing. if not, then i guess it just was attention seekers. there's no way to know. but it's better to accommodate for a few possible attention seekers than to shun a group of people with a legitimate orientation.
loling hard at "aloveuals"
what's so surprising about aloveuality? what is there to be gained from pretending you have no loveual attraction?
It's unlikely that 28% of people in a poll put anything other than Heteroloveual.
given the sample size, and that it's the internet, i'm not surprised it's 28%.
