FSI MIND

Its a very debatable topic. The reason why is that there's no straightforward answer; there are simply too many variables involved. Duration, intensity, effort, frequency, and even position all affect the number of calories burned during masturbation.

But to give you a sense of just how much of a workout you're getting, here's a stat: A 130-pound man will burn about seven calories for every five minutes of vigorous sex. Keeping in mind that vigorous sex uses a lot more muscles than going solo, don't expect to see people passing up on the gym in favor of porn and some good lube anytime soon.
