Washington, July 6 : Playboy boss Hugh Hefner's embarrassing sex experience that almost cost him his life is to be exposed in a new book.
The book 'Mr. Playboy: Hugh Hefner and the American Dream' by Steven Watts reveals the incident after conducting series of lengthy interviews with Hefner. The tome details the Playboy boss' history of shocking sexual escapades.
And Watts reveals not all the aging publishing mogul's romps were as steamy as admirers might imagine - Hefner once almost choked on a sex toy.
"Hefner divulges he almost died doing what he loves best while he was dating Playboy Playmate Sondra Theodore," Contactmusic quoted a source, as telling National Enquirer.
The incident is said to have occurred in 1977 when the pair were using a small sex toy that fell into Hefner's mouth.
The source added: "Hef began choking and was about to pass out. Sondra quickly started pumping his chest until the toy was dislodged."
The book is scheduled for release in October (08).
