Several months ago, a male colleague of mine received this Facebook message from a long-ago high school girlfriend: “I know you’re happily married, and so am I. But if you’re ever in Joburg, look me up. We could have some fun . . . no strings attached.”

Another guy I know received three sexual propositions on Facebook in a week—two from strangers, and one from a woman he used to work with. The former coworker, who was in a serious relationship at the time, sent my friend this private message: “Is it terrible if I told you that I really want to b_ _ _ you?”

Let’s be clear here: Women aren’t nearly as forward as men. The unsolicited messages in my own inbox, from strangers and former boyfriends alike, belong in the pages of a bodice-ripping romance novel. Facebook, it seems, has unleashed everyone’s inner freak.

And now we have a new survey of almost 3,000 people—1,377 men and 1,540 women—to prove it.
