Female here. But many have mistaken me for a boy. I've always been asked if I was either a boy or girl since I was little; I had boyish hair and never wore things like skirts or frilly clothing.
I'm only mistaken as a guy only when I cosplay but I have been mistaken out in public even when I don't cosplay since I occasionally like to wear some of my wigs out in public.
