Until I was 9, I was absolutely convinced that I had a penis [I'm a girl]. Now, I had seen naked babies before, so I knew that mine wasn't in my crotch. I thought I had a secret, hidden penis somewhere, and if I could just find it I'd be able to play with the boys and not be laughed at.
I could never understand why people would laugh so hard when I told them that I DID have a penis, I just lost it and needed to find it again! After all, they were girls and so had secret penises, too- they obviously just weren't looking hard enough!
