Nope. But so what?
The fact remains, just like indulging your self in nonessential foods, people often indulge themselves in non-reproductive sex. I suggest that if you're going to come down on people enjoying themselves in bed or on the kitchen table for no other reason than they like it, you'd better start coming down on everyone who eats a Snickers or a bag of Cheetos.
Which brings me to my question: Why is it you and conservative Christians/fundamentalists, pick on non-reproductive sex as your bugaboo, but not on nonessential fattening foods? My suspicion its that while sex itself is an embarrassing topic---god knows why, he invented it---eating fattening foods is not.
