There are a number of reasons to think twice (or three times, or four times, or fifty times) before sending a nude photo of yourself to someone electronically. But, if you're under the age of 18, there's at least one big, glaring, serious reason: you and the recipient could be charged with trafficking child pornography. If you think this sounds crazy, it is exactly what happened in Greensburg, Pennsylvania after two teenage girls send nude photos to some teenage boys.
