Does having too much sex really make you fat?! or does having too much sex really burn calories?!

Like any exercise...: Like any other exercise, the amount of weight gained or lost that day depends on whether or not having sex causes a person to eat more or eat fewer calories than she burns off that day. So, eating a box of chocolates after sex would cause a lot of weight gain after 12 days of sex and 24 trips to the godiva store.

No and No: Common sense will tell you. Weight is calories in, calories out. You're not taking in calories during romantic time, unless you are "plied with bonbons" as the song goes. You've done aerobic exercise that burns calories and know what it feels like -- sex is physiologically exciting but in a much different way. To stay a great lover, stay physically fit with diet and exercise.
