Photos: Sex and the Partridge Family's Shirley Jones

Much of Partridge Family star Shirley Jones' recently released autobiography deals with the late Jack Cassidy, the glossily handsome actor and singer whom she describes in a passage as her first lover and "sexual Svengali," and whose lessons she shares candidly. That includes — X-rated spoiler alert — Cassidy's impressive endowment, Jones' own "highly sexed" nature that made orgasms a breeze, their threesome with another woman ("yuck," she says, when asked about the onetime experiment), Cassidy's pre-marital sexual encounter with Cole Porter that Jones says left her unfazed, and her apparent tolerance for his infidelities. -- AP The book turns the image of a proper Shirley Jones on its head. Here are images from her past.
