This is a really interesting question and I would love to answer it but especially in society today just think super hard at what you perceive as masculine. To me (you can use this) I picture masculinity as strong and fierce mostly because that's just how I grew up and masculine means muscular and strong. Present-day definition wise of the word, I have no idea tbh. I guess it has though because mostly everything says masculinity is strong while feminent traits are normally shown as weak in media. For the last question, I would just answer it the best you can because the last one is really up to you.
