During the first meeting of U.S. Lesbian and Gay History on Thursday, Prof. George Chauncey gave students what he called a “parental advisory,” warning them in advance that his course would, indeed, cover sex.

“If you don’t want to read about men getting blow jobs in Central Park, this course may not be for you,” he said. “On the other hand, if that’s all you want to hear about… [well], then this course may also not be for you.”

Chauncey also assured students that they did not need to be gay to succeed in the class.

“The gay students don’t know any more about their history than you,” he said. “And I’m not even counting the freshmen, who may also be… undeclared.”
