These terms work as variations of transmasculine/transfeminine that explicitly have no attachment or barrier based on AGAB. Being transmascine/transfemine does not indicate a persons private information concerning genitalia and assigned gender. Rather, it simply indicates a trans person who’s gender (identity or expression) is wholly, or partially, masculine/feminine.
These terms include genderfluid, multigender, demigender, abinary, trans man/woman etc.
They can be used by anyone, but were particularly made for people who resonate with transmasculine/transfeminine but feel uncomfortable with it’s relation to AGAB or barriers based on such
