Penis Too Big?

I need to write this down now, so I never forget.  My three-year-old looks up at me while we are sitting on the couch and says, "Momeeee, my penis is too big!  I want it small again!!!" and I immediately started shaking with laughter.  I told him to leave it alone and it would go back down.  Now I'm wondering when that magical age is where they want it forever as big as humanly possible (or as non-humanly possible) so they can swagger when they walk, knowing that they carry a "big stick".  And, I wonder if there is an age where they get old enough to stop caring, like, maybe a hundred and twenty?

This reminds me of when John Campbell was about four years old.  He asked me where my penis was.  We had that talk and he acted genuinely sad for me because I didn't have one.
