I'v had these too, but after a detailed self diagnostic, I'v found that this happens mostly when en femme and been sidetracked into full male mode (some times a good movie can do this) and then you snap back into your immediate situation and notice the discrepancy.

That's a good 95% of the time for me anyway.

I also get it the Other way around too, when I'm pulled into girl mode and suddenly become conscious of what im wearing/sound like/look like etc...

I just smile at it now
