Men in their thirties and forties are less sexually satisfied than those in their fifties, a study has found. In fact, the baby boom generation are the most sexually satisfied of anyone outside their twenties, according to the research in the British Journal of Urology.

On a scale of zero to four – zero presumably being very unsatisfied, and four being Snoop Dogg - pentagenarians scored an average of 2.77, very close to the 2.79 recorded by the whippersnappers of the 20-29 age group.

Men in their forties came in with a satisfaction score of 2.72, but thirtysomethings could only muster a limp 2.55. Post-60, the men's sexual satisfaction tailed off. Doubtless they're worn out from the last decade's activities.

The survey was carried out on 1,185 men in Norway, hitherto famous for curling, whaling and binge drinking. ®
