is it possible to be cis but socially transition? and is there a label for socially transitioning only?
it depends. if you are coming out as openly cis, it's not a transition. other than that? possible. let me break this down:
someone comes out as a trans man. this person realized they are a cis woman after socially transitioning and chooses not to detransition
retransitioning or reidentification
experiencing multiple genders and one of them matches one's AGAB, this person may transition to one or more of such genders.
identifying as your AGAB but not exclusively, transitioning to non-binary, while still self-identifying as cis
being cissex but transgender (socially transitioning)
choosing to transition to another gender but not being such gender in the end of the day.
usually, transitioning is considered a trans* experience. but there are other gender modalities that include transitioning as part of their experience.
a label? sociotransitioned, sociotransitioning, sociotransitioner, sociotransition, sociotransitional.
