Guinevere (1999)

Harper Sloane is an awkward young woman who feels ill at ease in her rich and well-groomed family. When she meets and falls for much older photographer Connie, he gives her self-confidence as well as a sexual education. She discovers that he has a history of relationships with much younger women, and that she is the latest in a long line of protegees. But the relationship is a double-edged sword for both, and both have much to gain or to lose.
