How Often Do Men Think About Sex?
The average man thinks about sex every seven seconds.
Behind the Legend
According to an intense Kinsey Institute study, the average man forms a thought about sex approximately every two minutes, and that he generally ponders the thought for about a minute, 50 seconds before letting go of it.
An associated legend -- that every two minutes women think about shopping -- is blatantly sexist and completely without basis. It has been shown, however, that every two minutes a woman who is with a man will wish that he'd stop staring at her chest.
