while noting your experience, i do think it's good context to have that testosterone for trans men / transmasc folks can also improve their ability to process emotions and also generally their temperance (and personally, estrogen just makes me a goddamn wreck; i get depressed, irritable, cynical, etc)

(i worry that the anecdotes you've heard from trans women may be a little biased, as well 😅 i personally tend to think it's more about the right hormones, than what they are)

there's plenty about trauma itself that causes behaviorial instability. hormones may be a contributing factor in some situations, but i question how universal it is
