A new survey of sex therapists concluded that the optimal amount of time for sexual intercourse is 3 to 13 minutes. The median time for sex, from start to finish: 7.3 minutes. Now this figure does not count foreplay so as you consider your schedule, add time accordingly.

Researcher Eric Corty said he hopes these findings ease the minds of those who believe that more is better. Some might think if you really want to satisfy your partner, you should last forever. That's simply not true, he says. In this case, endurance is not critical for optimal performance.

"Most people's sex lives are not as exciting as other people think they are," says another researcher.

"People who read this will say, 'I last five minutes or my partner lasts 8 minutes,' and say, 'That's OK,'" Cordy says. "They will relax a little bit."

Does this news, to be published in the May issue of the Journal of Sexual Medicine help you relax?
