gender ambiguity

So I was working at the kiosk when a man, possibly, hopefully, crazy walked up to me and asked point-blank, "Are you a woman?" When I replied in the affirmative he just continued to stare at me, as if doubting my response. After a few long, uncomfortable seconds he replied, "I just wanted to make sure. Do you know where a map of this place is?" And then he was gone.

I was wearing a skirt and have boobies. Do I really look all that gender ambiguous?

I hope he was crazy, otherwise a serious makeover seems a necessity.
