Headcanon: everyone in the world is actually bi now (because of the need to have a partner when there are far fewer people now), apart from a few who are just straight – and they’re treated as weirdos. The gay people are technically bi, but just have a preference for one gender over another.
as a bisexual myself i love this hc
maybe the monosexuals (gay, straight, lesbian) only experience sexual/romantic attraction to one gender (like irl) but will settle for polyamory and/or QPR if needed because of the reason you gave, but ONLY if absolutely necessary.
idk hope im not erasing anyone here this is just my headcanon to your headcanon
Perfectly valid headcanon accepted here, mate!
