Genderfrithet 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 female. A genderfrithet person never experiences genders that are completely abinary (removed from masculinity or femininity). They are also never a binary woman. They can be a binary man. For example, a genderfirthet person could experience genders like man, androgyne, demiboy/demigirl, proxvir/juxera, libramasculine/librafeminine, etc. They would never experience genders like binary woman, neutrois, maverique, agender, etc.
History
The first apparent mention of genderfirthet is on Tumblr user Gender-Resource's April 2020 Gender Jargon list[1]. Coined at uncommongenders via Tumblr, with genderfrither and genderfrithen.[2]
Flag
The flag uses the colors representing male identities used in other genderfluid flags, and the colors used to represent female in those flags hueshifted to purple to represent never being a binary woman.
