The 55-year-old professor and his wife, who is ten years younger, write secret journals, each claiming they want to keep their notes hidden from the other. The husband is a voyeur and exhibitionist who hopes his wife will find his diary and be aroused, while the wife admits she finds her husband repulsive without his glasses. They complain about difficulties in their sex life. He feels she is insatiable; she feels his performance is inadequate.
