Men think about sex every 7 seconds

Sure, men can think with only one thing at a time: their brains or their penises. But how much does the latter really run the show?

Quick: What are you thinking about right now? Well, given that you're reading this article, it's probably sex. But there's a good chance you were thinking about it anyway. After all, men think about sex every seven seconds, right?

That's more than 500 times an hour and more than 8,000 times during the approximately 16 hours you're awake. We can only imagine how those numbers fluctuate during sleep.
