Fisher is a psychologist at The Ohio State University, Mansfield. She is one of the people that heard that old chestnut, "A guy thinks about sex every seven seconds." Well, she decided to use the resources at her disposal to see if that was true.
The results of her research as reported to LiveScience? Turns out guys think about sex 18 times a day. Several men recorded thinking about sex only once a day. (One guy reported 388 thoughts in a day. That's kind of yikes, but if you allow time for sleep, that still works out to thinking about sex every 158 seconds, which still isn't every seven seconds.)
I can hear you women laughing. And you know what? She found that women think about sex an average of 10 times a day. Okay, not as much as guys, but the old stereotype of, "Men think about it constantly and women think about it never?" It's a bunch of crap. Sex isn't the only thing men think about more than women. They also think about sleep and food more than women.
And so, next time someone tells you you are either thinking about sex or about to, you now have clinical proof they are wrong. Science marches on.
