Monogamy is unnatural: Hugh Hefner

Hugh Hefner could swear on his faithfulness to fiancee Crystal Harris, but insists he finds monogamy unnatural.

The 85-year-old founder of soft-porn magazine Playboy, who is famed for dating multiple women at the same time, is preparing to marry Crystal Harris later this month, and insists he is a good husband who intends to remain faithful, though he feels it could be difficult.

"I'm totally capable of being a good husband. I can be devoted, sensitive. Faithful? Yes. Absolutely," Contactmusic quoted him as saying.

"I do think that monogamy is possible. I just don't think it's the natural way of things," he added.
