I don't when I'm wearing female clothing. When dressed up in boy's clothes I get called "he", as expected, most of the time. Which is sort of the point - if I wasn't then there'd be no point in wearing them. I do, oddly, get stared at quite openly and have been asked more than once if I was a female to male transgender!!! I can't blame people for that; my body language is all wrong for boy.
I suppose that's working for me at the moment, although misgendering is too easy. I did it myself last night!!!

Luckily nobody noticed. I was upstairs at a community centre with a few friends and the door was open on to the staircase. We heard someone come in and one of the group was like: "That will be .... I don't think you've met her yet."
And I said: "No, I'm pretty sure I haven't met her, but I would like to". At which point the person, still downstairs and unseen, spoke. I heard and, shamefully, blurted out my first thought: "Oh that's probably not her; it sounds like a boy has come in."
Bear with me, or try to, it was an open event so entirely possible that the new person coming in was male. But, as you may have worked out, I was the one who was wrong. It's not like my voice is fantastic either; it's only good enough to creep into 'woman who sounds like a man' - but nothing changes the fact that I misgendered.
Having said that, there were reasons for doing so?

Almost everyone gets misgendered at times. Well everyone toward the middle of the gender poles I suppose, me included. By that I mean assuming me to be female when I'm attempting to dress male.
p.s. I know said person didn't hear me, which may be worse if anything, but I'm still so embarrassed about what I did. Which was nothing more onerous than making an assumption, it's hardly like I'm going to be prejudiced. I don't have any of those!! They didn't hear me, and I saw no need to tell them as that would just reinforce something potentially negative. What's a girl to do?

Blerrrgh - I wanted to crawl into a hole at that point.
