Today's interesting egg realization: from an early age, I was deeply avoidant of locker rooms. I didn't understand the reason, I figured I was just shy, or afraid other boys would mock me, but I knew deep in my heart that this was a place to not be. I don't recall ever being unclothed in a locker room.
As usual with these realizations, it all makes a lot more sense now. (And this isn't to say that locker rooms are a nice place for anyone else, I suspect they're just generally not good.)
