Sit. Stay. Roll onto me. I learned everything I know about sex from my dog.

As I was stroking my best friend's ears Saturday night,(and yes, my dog was there, too) it struck me how similarly I'd trained both.

My dog waits impatiently as he watches me dabble in debauchery. "Get on with it," his eyes say, as I'm rolling in a tangled mess of sheets, arms and hard breathing. When the bed surface calms to a gentle rocking, he'll launch himself into the middle, hoping for a clear spot to land.

My two (or sometimes three-legged) friends- well, they've perfected the exaggerated eyeroll in lieu of puppy dog eyes. They look around, and when I'm discovered in flagrante delicto, they heave a histrionic sigh and announce, "Well, she's as good as gone for a while." Being human apparently means that they know better than to jump into a mess.

On the other hand, humping a pillow clearly transcends man-animal boundaries.

When I was a yearning little girl, my pillow could be smoothed into the broad shoulders of my heartthrob. And if a little pelvic thrust came into play at a pivotal fantasy moment, well, who would be the wiser? The Dog-King, possessed of a fleeting hormonal urge, frankly hops into position and wildly humps for 20 or 30 seconds... eventually becoming distracted by a passing siren or Shiz-tzu.

It appears we have more in common than not. And so when I observed a pack of well-heeled homo sapiens indulging in that most animalistic of pleasures in my living room Saturday night, I simply had to hand it to those naughty dawgs.

But it was one at time, buster-- one at a time.
