We all know that college students hit the books hard. But as it turns out, they’re also hitting each other, with riding crops, belts, paddles, canes, and floggers. “Floggers are my favorite,” Says a Harvard Junior, who goes by “Maria” in this article by the New York Observer. BDSM (short for bondage, discipline, sadism and masochism) has been around since the beginning of sex. But the accelerated mainstream acceptance of these practices may have something to do with the rise in popularity of erotic novels such as Fifty Shades of Grey. This acceleration is most apparent in Ivy league colleges such as Columbia, Tufts, MIT, Yale and Harvard. All of these schools offer unofficial “Munch groups.” A munch group  is an informal gathering to eat and socialize and discuss their interest in kinky sex. The Harvard College Munch group has been meeting casually since October of 2011, growing from 7 members to 20. Tomorrow, it will be ratified as an official club by Harvard's student-life committee. This means more privileges for the members, more recognition from the school, and more opportunity for students to discuss the issues that are important to them.
