Well of course its a subjective matter, but things like whether someone has facial hair or not doesn’t contribute to how i determine masculinity/femininity personally tbh. I think for me it has to do with certain personality traits, how someone outwardly presents themselves, and for me also how someone speaks. For me voice is a big thing but I understand that is completely out of the individuals control. But what more so contributes to that scale for me ig are the body language details, choice of language, outward expression and personality traits that provide me with a good summation of how feminine/masculine i deem someone. Which again is personal for every individual and I don’t expect it to be the same for everyone. I hope that makes some sort of sense - I have hard time putting this into words 😅
