Why no be yourself and just do what you do rather than define yourself as a title? There is no need to make things complicated. Sometimes it better to be vague or have a lack of adjectives. Like if one wanted to describe the temperature would say it is hot outside or hellishly hot, no wait it is freaking hot because it is not quite hot as hot or hot as hellishly hot.
Basically if you don't want to complicate things then all you need are few different shades of grey or a few select colors of a rainbow rather than several variant of colors to describe each niche.
I'm not saying we need these super long obnoxious "demistuffstainlolthisjokeisdu
mbasforgetloveual" titles. Those sound sort of ridiculous to me.
You said yourself to use a few different shades of color to describe ourselves, and that's exactly what heteroloveual, homoloveual, biloveual, aloveual, and transgender/tranloveual do. Those are the only terms I honestly recognize as legit because, surprise surprise, the psychological and biological communities do too.
