I am feminine because I was born a female and my gender identity happens to match. That is why I’m feminine. I’m feminine whether I’m working on my bike, changing my car oil, playing football, or sewing a dress. None of things impact my level of femininity. It just is. it’s innate. It just is.
To the girl in class who thinks I’m masculine when I change my car oil(which I have no idea how to do). I’m not and you aren’t either.
