From the age of six, Jennifer Saginor (pictured) now 51, spent her childhood at the infamous LA party spot and had a room of her own in the 29-bedroom mansion from the age of 12. Now, Saginor tells DailyMail.com in an exclusive interview: 'In my head, it was the most magical, Disneyland environment that a kid could ask for.' But, she explains, 'as the years went on, I didn't realize some of the boundaries being crossed by the adults would be something that would affect me for years to come.' Saginor, who has written a memoir about her childhood, says Playboy boss Hugh Hefner (left and top right) was like an 'uncle' and would have his butlers cater to her every whim, whether a cheeseburger for lunch or a ride to school in the Playboy limo. The reason was her father: Dr. Mark Saginor (left, in gray) Hef's personal physician and close friend who was nicknamed 'Dr. Feelgood' due to his propensity for dishing out prescription pills. She describes how he encouraged Saginor and her sister to embrace nudity, took her clubbing at 15, and kept three jars filled with pills in the kitchen of the Beverly Hills family home labeled 'uppers', 'downers' and 'quaaludes'. But most of their time was spent at the mansion, exposing the glamorous blonde to shenanigans that included naked parties, parades of porn stars such as Ron Jeremy constantly in the home and big screen TVs that showed erotica on a loop.
