London, Apr 29: An American woman has revealed how she pledged a year of sex to her husband as a gift for his 40th birthday, and how it changed their lives.
Charla Muller, 42, from North Carolina, USA, even went on to write a book about the experience she had with her hubby salesman Brad, who is now 42.
The mother of two started out by telling how her husband literally fell over when he heard the offer, and how he even refused it.
