It looks as though men had it right all along: It doesn't take long to satisfy a woman in bed.

A recent survey of sex therapists has concluded the optimal amount of time for sexual intercourse was 3 to 13 minutes. The findings, to be published in the May issue of the Journal of Sexual Medicine, cast doubt on the notion that staying power is the key to great sex.

research has shown that both men and women want foreplay and sexual intercourse to last longer

But take caution before celebrating guys,the time does not count foreplay, and the therapists did rate sexual intercourse that lasts from 1 to 2 minutes as "too short."

Eric Corty who lead the research team said he hoped to ease the minds of those who believe that "more of something good is better, and if you really want to satisfy your partner, you should last forever."

The questions were not gender-specific, said Corty, adding that prior research has shown that both men and women want foreplay and sexual intercourse to last longer.

In a similar study back in 2005 a Dr. Irwin Goldstein, of the Journal of Sexual Medicine, quoted a four-week study of 1,500 couples that concluded the prime amount of time for sexual intercourse was 7.3 minutes, who actually timed the sessions remains unclear.

Both older men and young men tend to struggle to make sexual intercourse last much longer than the 3 to 13 minutes and although there are myths of what other people are doing sexually, most people and cultures sex lives are not as exciting as they are portrayed.

The results of the studies are intended to give therapists guide lines of what is normal and satisfactory among the couples they see.
