The Harrad Experiment

At Harrad College, where controversial coed living situations are established, the students are forced to confront their sexuality in ways that society previously shunned. Part of the experiment is to pair incompatible members of the opposite sex as roommates in order to make them shun the traditional concept of monogamy. The film's primary two "couples" are the sex-crazed Stanley and ultra-timid Sheila, and insecure Harry and liberated Beth. In charge of the "experiment" are Prof. Philip Tenhausen and his wife, Margaret, who seem to enjoy the tension they instigate, as well as the graphic sexual episodes that unfold. - IMDb
