As Walter Christensen, a 53-year-old physics professor from Pomona, California, discovered, when it comes to cuddling, women know what they want. When he and his lover spend the night together, he's usually awoken around 3 a.m. with a familiar request.

"She calls out, 'Spoon, spoon!'" he says. He willingly obliges with front-to-back cuddling -- even though he admits he probably wouldn't do so without being asked.

"I like the feeling of her wanting to do that," he says, "so I do it out of a sense of responsibility."
