It has nothing to do with hormones . Except you ' re completely wrong . Fear IS tied to testosterone levels . I HATE how you gender denialists keep on spouting that same old tired socialization red hearing for every damn behavioral disparity between males and females . Before even researching the possibility that hormones play a role in the biological fear response , you have an embarassing kneejerk response to say No ! It ' s all society ' s fault , neurophysiology isn ' t real ! Endocrinology isn ' t real ! Developmental biology isn ' t real ! We KNOW now that gender differences results from both nature AND nurture , not either or as biological determinists and social constructionists argued in the mid 20 th century . Educate yourself on the matter here . The FtM man is telling the damn truth about his own HRT experience , that testosterone reduced the fear he had around other men . Don ' t fucking shove your halfbaked gender socialization theory down his throat to invalidate his experience .
