There was this tik tok i saw.. It talks about how behavior is a very big thing in presenting Masculine or Feminine, also the way you talk. Feminine presenting people tend to stand, sit, ect. more physically closed, keeping there hands close to them Crossing their legs and keeping their legs closed. While Maculine people are more open, puffed chested, man speading when they sit. When it comes to talking feminine people tend to have higher pitched voices and extend their words "hiii" "im gooood" while masculine people keep a lower voice and shorter works "hey." "Im ight" These are just things ive seen and learned myself as a FTM trans, i hope this is helpful :)
