In 1980, AC/DC sang “You Shook Me All Night Long.” And since then, many recording artists – think Prince, Faith Evans and Rhianna – have allusions of all-night sex in their lyrics.
But, can you really go “all night long?”
A new study, published today in the international Journal of Sexual Medicine, says the best sex should last seven to 13 minutes, it is being reported by news.com.au/heraldsun.
And get this: Even three-minute sex is considered “adequate.”
According to the study, which included a random sample of Americans and Canadians, sex longer than 13 minutes was “too long.”
Americans usually expect intercourse to last between 15 to 20 minutes, according to other U.S. studies, so this new study is designed to have a calming effect on couples who think healthy sex has to last a long time.
The study also aims to help calm couples' unrealistic beliefs that healthy sex should last a long time.
"Usually women are quite happy with short intercourse, and are not bothered about prolonging it at all, but nearly all men want it to be much, much longer," Dr. Jane Howard, a medical sex therapist from Brisbane, Australia, told news.com.au.
