Hugh Hefner always invites more women than men to his parties.
The Playboy founder - who currently has three young blonde live-in girlfriends, 20-year-old twins Kristina and Karissa Shannon and 23-year-old Crystal Harris -has shared the secret for making the perfect soiree at his Playboy mansion in Los Angeles.
He said: "A party with a bunch of guys looking to get lucky is a poor party. We solve that problem by having a ration of 2:1 females over males."
The 83-year-old renowned ladies' man didn't however provide a formula for what the ratio would need to be if a woman wanted to get lucky.
The media mogul - who once admitted he almost died from choking on a sex toy - also recently revealed that he prefers to spend most of his time in bed, doing as many activities as possible there, rather than holding parties.
He said: "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."
