British men have the worst sex lives while Canadians have the best, a new research published by the Journal of Sex and Marital Therapy says.
The new data reveals that three out of 10 British men have not had sex in the last 12 months, and only 70 per cent of men in Britain have had sex in the last year.
The journal also reports that the number of sexually active women in Britain is below 60 per cent.
The research, based on 6,000 people in the age group of 40 to 80, in Britain, the US, Canada, Australia and New Zealand, shows large differences in sexual activity.
It says in the US, Australia and Canada, 80 per cent of men are 'sexually active' -- those who have had sex at least once in the previous year.
In Britain, 41 per cent of British men and 33 per cent of women are 'very sexually active' -- those who have had sex at least once in the previous week.
New Zealand was the only country where more women than men were termed as very sexually active.
