Being androgynous, and being treated as such, means your treatment is usually relative to your overall demeanor, or signals you are giving as out the original poster stated.
I live my life in an androgynous state and occasionally going on either extreme of the gender role. However, because my voice is so feminine, and my movement and overall appearance is so feminine, that most people default to calling me a she, and treating me as such. Oddly enough, If I tell people that I'm actually a boy, they still treat me like a girl.
Usually things are never awkward. As long as you are confident with yourself and who you are, then people will treat you with respect... And treat you like a human.
