I just read that sex increases your heart-rate about the same as going up two flights of stairs and burns about 5 calories a minute...
meaning that you'd have to be going at it for 12 hours to burn off a pound!
On the first two I thought, "Somebody isn't doing it right!"

...
on the 12 hour stat, I've decided that it'd be worth it and I'm willing to try!

On a related note... I just saw a pictorial with some of Sophia Loren's sexiest pictures...
Pretty nice "eye-candy" from the second most beautiful woman in the world! Right Van-Sensei?
(Remember, I married
the most beautiul woman in the world...)
