Hugh Hefner almost died having sex.

The 83-year-old Playboy publisher, who is currently dating Crystal Harris and twins Karissa and Kristina Shannon, choked on a sex toy while in bed with a group of his girlfriends.

He revealed: "What is the closest I've come to death? There was a moment when I was having sex with four Playmates and I almost swallowed a Ben Wa ball."

The media mogul also revealed he prefers to spend most of his time in bed, doing as many activities as possible there.

He added: "My most treasured possession is my rotating round bed.

"I don't have dinner parties ? I eat my dinner in bed. I relax with my girls in bed, just watching a movie and having a good time.

"If I had to dress up in fancy dress, I'd wear my pyjamas."

However, Hefner admits the aging process is starting to affect his sleep patterns.

He said: "I need to go to the toilet several times a night ? that comes with age."
