The easiest way to 'male fail'.. is to pluck your eyebrows into a nice feminine shape.. you could be on day zero of HRT.. Likewise, you can be on day 6432 of HRT and don't shave or put on fake beard - and pass as male.. so, the whole premise is a bit flawed..
However, I started to 'male fail' a lot earlier than I realised, only looking back does it now make a lot more sense. Walking into a men's room and someone saying 'Hey, love this is the men's' - me then being so embarrased that I ran into a cubicle and they started laughing.. to the waitress, who was serving us at our table, came back to check on us and asked 'Everything okay ladies'.. embarrassing as I was with my then wife.
All of these things happened over 12 months before I transitioned at a time when I was not intent on actually transitioning. So at the time I was almost ashamed of them (though inside my head they were little victories).. I had not started oestrogen at all either - however, my body does make it's own so not exactly without any help.. But I still stand with my premise - HRT is not what is making you male fail, your want to do so is.
