Watch The Sexperiment (1998) Official Trailer

Two sexologists make a bet: that they can induce two fellow researchers to shed their inhibitions by exposing them to a series of interviews with people who recount their erotic adventures. The two "subjects" are told that they are supposed to write summaries of the stories they will hear. The "sexperiment" works: Candace and Peter fall for each other, but they also discover that they have been manipulated.
