transmasc - someone whose identity has become more masculine after overcoming social pressure to be feminine
transfem - someone whose identity has become more feminine after overcoming social pressure to be masculine
crucially, these definitions are broad enough that:
- a trans person coerced into a male identity at birth, whose transition let them safely experiment with masculinity is transmasc
- femboys can be transfem
- a gay cis male bottom who unlearns the idea that male bottoms must act femininely is transmasc
this shift in definition not only unshackles us from our coerced sex, it also lets us interrogate more ways that gender norms are imposed on us
if this makes you uncomfortable, try to figure out what part of people you actually want to talk about. if it turns out that you just want to talk about birth sex, that may be worth interogating.
