I was always under the impression that to be a man meant that you always had to be the big spoon. It was the position of power and control. You also got to be the protector and provider of warmth.
Since being married, I now have the possibility of spooning every night and for long periods of time. However, that has turned the above ideal into awkward placements of the mattress side arm, mouthfuls of hair which always tickles your face first, and getting way too hot.
Being wiser and more married-er, I've discovered that a key to marital bliss actually lies in being the small spoon! The wifey still feels secure and warm wrapping herself around you, your arm no longer needs to go numb under her head (for some reason this isn't as big of a deal for women), and you can breathe easy, hair-free, AND have full control of the blanket thermostat (ie. how much you are in or out of the covers). You can take that to the bank.
