Apparently boys' fascination with their ding-dongs starts really early.  As soon as Tyler was old enough to find that thing with his hand (before he could even walk), it became like a magnet.  As soon as the diaper came off, the hand went to it.  When he was old enough to sit up in the tub himself, he started having a grand old time exploring.  What really surprised me, though was the amount of abuse his poor privates take.  He grabs it, stretches it, pulls on it, and generally treats it like it was Stretch Armstrong! 

One day he was in the tub, grabbed the skin on his penis, and pulled it striaght out from his body, forming a "v" shape on either side of his pee-pee, then he giggles, looks at me and says "mommy, I made a bunny with my pee-pee!".  All I could think was "dude, doesn't that hurt?!?"  I was cringing, and I'm not even a guy!  :)
