JAMES R. PETERSEN was the sex editor for Playboy magazine for almost 40 years. He likes to say he wrote about sex when sex was new, when it was something you did in person. Now retired, he gets his breaking news from the History Channel. He discovered live storytelling last year and has since performed at more than a dozen Moth StorySLAMs, as well as in bars, backrooms, coffee shops, art centers, armories, and someplace in Milwaukee, some of which were actually hosting story events. He says that he will never again write for print. Paper doesn't listen, laugh, gasp, or fall asleep.
