London, Nov 9 : Foreplay - the 'naughty' things done before getting on to sex -is overrated, finds a new study based on 2,300 women.
According to the survey, when it comes to the likelihood of having an orgasm, foreplay has little or no significance.
On an average, the duration of intercourse is 16.2 minutes on average, and it is the clincher.
The research's findings suggest that sex therapists, who emphasize the value of foreplay, may have that been getting it wrong.
"In contrast to the assumptions of many sex therapists and educators, more attention should be given to improve the quality and duration of intercourse rather than foreplay," the Telegraph quoted Professor Stuart Brody of the University of the West of Scotland, and Professor Peter Weiss, from Charles University, Prague.
The study has been published in the Journal of Sexual Medicine.
In the study, the researchers asked a representative sample of 2,360 Czech women of all ages about details of their sex lives, including orgasmic consistency with a partner along with estimated duration of foreplay and intercourse.
The analysis revealed that for the women in the study, the average duration of foreplay was 15.4 minutes, and intercourse, 16.2 minutes.
In the study, the boffins looked at frequency of orgasm in the women, and foreplay and intercourse data. They concluded the links with foreplay were insignificant. Instead they suggest that the longer intercourse lasts, the greater the probability of orgasm for the women.
"This was a large number of women and the results are robust," says Professor Brody.
"Sex therapists and educators put the overwhelming emphasis on foreplay, but they need to be guided by the evidence which shows that it is not the case.
"Intercourse is significantly more important. Our findings should lead researchers, educators, and clinicians to reconsider the contributions of foreplay and intercourse," the expert added.
