Genderfrithen

Genderfirthen is a form of genderfluidity in which someone is only fluid between genders that are in some way connected to masculinity or femininity, but they are never completely male or completely female. A genderfirthen person never experiences genders that are completely abinary (removed from masculinity or femininity). They are also never a binary man or binary woman. For example, a genderfirthen person could experience genders like androgyne, demiboy/demigirl, proxvir/juxera, libramasculine/librafeminine, etc. They would never experience genders like binary man, binary woman, neutrois, maverique, agender, etc.

History
The first apparent mention of genderfirthen is on Tumblr user Gender-Resource's April 2020 Gender Jargon list. There does not appear to be any other coining post. No flag for the term exists.
