Movies like The Misadventures of Margaret

A timid, insecure popular author with an overly-attentive professor husband decide to write an erotic novel. With encouragement from her sister and a bi-sexual friend, she goes to France with the intent of doing research at an inn where a diary she had been using documented erotic encounters. Instead she finds the inn is now a cloister for singing nuns. However, a young, divorced sound engineer is also there taping the nuns. While attracted, she mostly succumbs only to new fantasies until he follows her home to New York.
