To expand on my previous comment I have just thought of an analogy, imagine that you are trying to photograph someone who is posing, these sort of photographs rarely come out showing the true way that a person appears in everyday life, they just look unnatural, not quite right. Then think about photographs taken of people who are unaware of being photographed, they look very natural, and different from a posed shot.................so if you are thinking about "your performance" and how you look to to others, it's much the same as posing. I know that you will probably feel under more scrutiny in the "bogs" than in many other places, please ignore that feeling, and never ever give in to it. You just have to get on with what you're doing and ignore others, yes some may be unsure of your gender, but they won't ever be sure if you just get on with whatever you're doing, it can be likened to a poker game, are they going to call you if they aren't sure, and risk of making an absolute arse out themselves............?
