You Asked: How many calories does sex burn?

Of all the ways a person could sweat, a roll in the hay is one of the most fun. But does sex actually burn a good number of calories?

Not as many as you think—but you can up your burn by doing it a certain way.

One study found that sex burned more than 100 calories, at least for men. A team from the University of Montreal compared the calorie expenditure of running to that of sex and found that—no surprise—running far outpaced the latter.
