well i pretty much passed my whole life even as a little kid (with a shoulder length long hair cut as well) everyone who didnt personally know me "thought" i was a boy. Even when people who didnt know me referred to me as my parents' "son" saying "your son" and "he" is handsome or whatever they said etc, my parents just let it go at that and didnt correct them. They always supported me being a "tomboy", never made me wear a dress cause i didnt want to, bought me boys toys cause i wanted them and >-bleeped-< like that. I told them i "wanted" to be a boy when i was really young, then came out as trans when i learned what being trans was when i was 10 years old. Am really grateful for their support.
