If I was thin, had long hair, and shaved really closely I got called a girl. I think I overcompensated by building a lot of muscle, growing a beard (was pretty good at that sadly - not I'm having fun getting rid of it!), and kept my hair really short. Also my T was always quite low anyway so stuff never really worked as it should have. E didn't really have all that much work to do in terms of 'passing'.
