Boyfluid people shift between male, neutral, and androgynous identities, but they don’t include female ones. Neogirlflux people move between Neogirl and Agender, with some feminine aspects in between but never really feeling fully female.
Genderfaunet people are all about experiencing different genders like male, masculine, non-binary, and sometimes feminine ones, but they never feel completely female.
So, if you’re both boyfluid and neogirlflux, you’d be navigating a range of genders and experiencing some feminine elements, but you wouldn’t feel fully female.
In other words, being both //would// fit with being genderfaunet, because you’d be engaging with various genders without fully identifying as female.
