I grew up with 3brothers and no sisters so Id no female influence in my life except my Mother. When I transition, guys holding doors open for me, insistent on walking me home or getting a cab for me on a dark night was a little scary at first, I remember a guy at school who was a typical bully, a nasty guy, I met him many years later after my transition, he didn't recognize me, but just saw me as a woman, he was like a different person, he was horrible to other guys, but sweet and charming around women, it was weird, well he wasn't my kind of guy, I remember discussing it afterwards with my mother, who just laughed it off, welcome to womanhood.
It took me a while getting used to it, like the time when a young mother on a train ticked off her young son to have manners, give up his seat for the lady, she smiled at me and I smiled back, her son wasn't pleased, it starts at a young age.
