Has the world not seen enough celebrity sex tapes and nude photos? Every other day, a new blowjob video or a pixilated snapshot of an errant breast is leaked to the Internet. According to Wired Science, this desire to share skin has less to do with fame, and more to do with neuroscience.

Being admired is a turn on for women. From Wired - “Studies have found that more than half of women’s sexual fantasies reflect the desire to be sexually irresistible.” What turns men on? Naked bodies. Sounds like a perfect combo. No woman wants to be objectified or seen purely for her body. However, the college co-eds in Girls Gone Wild seem more eager to expose their breasts than their brains. (Or perhaps those racy shots of girls flaunting their intelligence and good judgment were left on the cutting room floor.) Of course, there are many men who expose themselves as well – “At any given moment, one in four cameras on the webcam network ChatRoulette are aimed at a penis.” Which is strange, considering that few women are turned on by disembodied sexual organs. Though straight men will pay all kinds of pennies to watch naked female bodies and body parts online, “not a single website collects cash from ladies interested in surveying amateur photography of phalluses… Women feel the conscious desire to catch the universally attentive male eye, but since women’s erotic attention is rarely ensnared by a penis, the male exhibitionist urge is comparatively vestigial.” Fascinating stuff. We'd love to hear your thoughts. In the meantime, click the photo above for an artistic shot of Scarlett Johansson’s naked butt. (Probably NSFW, unless you work for a vibrator company).
