I sometimes call myself 'she' in my mind, just out of habit. I've been trying to correct myself, but I just can't seem to settle on a name that I can call myself instead of my birth name.
Yet, I sometimes find myself unnecessarily surprised when I call myself 'he' or 'man' or 'boy' in my mind unconsciously. I'm happy at those moments, because it confirms that my unconscious mind knows what I am.
I hate the gender boxes. If it's for something unofficial, like a website, I check male, but for official records, I hold my breath and check female, then cover it up with a paper or a pencil so I don't have to look at the horrible mark. It should be a law to have an 'other' box or something like it on all forms.
