The Minnesota Fringe is the biggest festival of its kind in the U.S., boasting 25 venues and hundreds of performances in a single two-week period. And while many fringe festivals have embraced politics this year, the Minnesota Fringers have gone a different way. Specifically, a shocking number of this year’s productions are focused, laserlike, on sex, which wouldn’t be surprising in, say, New York, but which seems a tad out of place in the buttoned-up Midwest. The Fringe’s director has an explanation: “A lot of it is the Teen Fringe. We don’t censor the teens, and it turns out that when you let teens talk about whatever they want, they talk about sex.”
