Given that I have spent most of my life living and socialising as a guy, I pretty much know the rules and ropes... So, I can pass as male - lets say, I had to wear my L size suit for official job purposes and people did not roll their eyes when they saw me - maybe a couple of extra checking stares from police security personnel, but as long as my picture in ID matches my face, there are no questions. I do get some sideglances in male restrooms, but I usually walk in with confidence, shoulders wide and posture straight (and if questioned, I can drop my voice down really low) - anyway, there are far less consequences for being considered female in male restroom than vice versa.
As for daily routines, I have little clues for how other people see me and language is very much gender neutral (I can speak about myself in gender neutral language, avoiding gendered constructions and forms) and we very rarely use the equivalent of "Sir" or "Miss" here. But I have realised that there are situations when no matter what I wear or what I think about my looks, people would gender me female nevertheless.
Technically, I am not full-time, although I do not wear distinctive male clothes (with some exceptions when for work reasons I simply must put on power suit in order to to speak to government), at the same time, when I wear more female-leaning outfits, people do not give extra stares or bat their eyes - on the contrary, I am catching much more stares when wearing flat, baggy male winter attire...
