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.
