Once I'd finished my male puberty at about age 19 or so I was far too male anatomically to pass as female even when I wore androgynous clothes and had long hair after that point I only wore plan black clothes and hid my body it wasn't possible for me to remove my facial hair no matter how much I pulled out and how long it took was just too thick and too painful. So I gave up trying to be andro-female as had been my coping mechanism it only articulated everything that I wasn't anymore :/
It was 3 and abit years when I started transitioning that I was taken for female, But even before then in my teen years it wasn't a common thing perhaps once every 6 months or so.
