The reason women scream during labor is because they're excited it's almost over. It has nothing to do with a bouncing baby entering this world through such a small orifice. They don't call a baby's birth a miracle for nothing. Easy! Piece of cake! That's why men don't have babies; they're tough and need something much more difficult to do, say, maybe trying not to puke while changing a dirty diaper. lol
I just couldn't help myself.
