Jack Stuef reports on an exhibitionist subculture:

Out of the over 3.8 million articles Wikipedia says it has now, the page for "autofellatio" is the 3110th most visited. It describes autofellatio as "the act of oral stimulation of one's own penis as a form of masturbation." Like many Wikipedia entries, this one features a photograph of what it’s describing. Jiffman wanted to be the guy in that photo. When people looked up autofellatio, he wanted them to see him doing it. But he wasn’t the only one.
