It's good for causal conversation I suppose. But I'm very suspicious of the accuracy. It's almost for certain self reported:

An international survey of 40,000 men has revealed 60 per cent of Australian men have never strayed, ranking just behind the Germans and Poles at 62 per cent.

South Korean men are having sex more times a week than anyone else in the world, while hot-blooded Brazilian men are at it with a wider range of women.

On average, South Koreans said they were having sex at least four times a week, while Filipinos were world-beaters at masturbation, doing it almost six times a week.

Brazilians topped two categories, with 19 per cent saying they had had a threesome, which might help account for them having clocked up the most lovers, the internationally published fitness magazine said.

British men spend or claim to spend an average of 17.44 minutes on foreplay per sex session, longer than Australians (17.2 mins), Germans (16.92 mins) and Mexicans (16.91 mins).

But British men last only 18.64 minutes from foreplay to climax, far behind the Mexicans (23.17 minutes) and the Dutch (22.42 minutes).

Women might want to keep an eye out for an Italian lover 60 per cent of Italian men said they made their partner climax every time.

Now if they wanted to do a real study they need to have unbiased scientific observers. Dr. Joe is available for the right price.
