I read the most amazing thing in The Chronicle today, "Six percent of Americans over 18 have sent a nude or near-nude image of themselves to someone else and 15 percent have received one, according to the Pew Research Center's Internet & American Life Project." I'll have to think about this more, but off hand, it would appear that on average, every person who sends a naked (or nearly so) picture of themselves, sends one to 2.5 people. Does this mean people are 2.5 times as likely to be voyeurs (perhaps unwilling ones) as exhibitionists?
