Naming IT

Why is it that men have to name IT? Why? Really someone tell me? I know not EVERY man has a name for IT but I know of more who do than who do not. Usually it's a stupid name too. Why is that? How many call it "little friend" "Love Muscle" Or "Love Rocket"? Not very original. My personal favorite 'Little Elvis'. That is so funny and cute. Of course I don't think I could EVER refer to IT as 'Little Elvis' - honestly what woman calls her partners *ahem* by THAT special name he has given it? Who really? It's all kind of silly... but 'Little Elvis', that's cute.
