Ma Vie Sexuelle is a modern tale of Parisian romance. The film's originality, and humour lie in its superb performances for which Mathieu Amalric won a César Award for Best Newcomer in his role as Paul. Paul is a fiercely intellectual, woman-loving assistant professor at the university of Paris. He became a teacher but hasn't finished his doctorate that would make him a full professor. In this state, on a modest salary, he lives a half-life waiting to begin what he calls "his life as a man". Paul has been dating Esther for ten years. They don't get along, in fact, they are on the verge of splitting up. Two years ago, he had an affair with his best friend's girlfriend.
