I used to get it a lot when I was younger, in fact I even had a teacher ask if I was a boy or a girl which lead to quite a large amount of ridicule from my classmates. It's rarer now and usually only when I'm wearing male clothing do people assume I'm male and usually only from a short distance, cosplaying or regularly.
But, eh, I wear what I want and tend not to worry too much on gender anyway. I personally think I make a poor crossplayer but then again, I can also suck at regular cosplaying. I blame my weird facial structure. But oh well, it's what I have fun doing so I'll keep at it.
