If you want to send a nude (and have a willing participant), then send a nude. That number may even be higher now, as the study came out just as Snapchat, then an ephemeral multimedia messaging platform built around disappearing photos and video, was taking off. In a 2013 study, about 27% of all smartphone users said they receive sexts on a regular basis, and 12% admitted to sending nudes (though the people polled may have been being coy). If you've ever sent or received a sext, you're not alone.
