Twice as much bang for your buck
Results show that for the women in the study, the average duration of foreplay was 15.4 minutes, and intercourse, 16.2 minutes.
The researchers point out that 16.2 minutes is considerably longer than reported in American studies, where intercourse was found to last on average seven minutes.
They added: "It could be that this reflects, a greater appreciation of intercourse and sensuality by Europeans than by Americans."
I couldn't possibly comment except to note that the researchers clam to show that all that faffing about before the main event has " little or no significance when it comes to the likelihood of having an orgasm". So it looks like American efficiency proves yet again to be just as effective but only takes half the time at much less effort.
