You'd be forgiven for thinking that we humans do nothing but talk about sex. But even when us amorous apes actually stop doing the jaw-jaw and get down to business, there's still one question haunting our horny brains: just how long should sex last?
If you're Sting or Puff Daddy, you'd probably say sex should go on for at least the length of a bank holiday weekend. Whilst if you're an inexperienced spotty teenager, you'll probably be delighted if the time taken to complete a dirty deed matches the duration of an average Ariana Grande tune.
Now science has weighed in (again) to tell the world exactly how much time they should be spending in the act of physical love: 5.4 minutes.
This study found that sexy time lasts anywhere between 33 seconds and 44 minutes, with the median time coming in at 5.4 minutes.
Dr Brendan Zietsch recounts a study in which 500 couples were armed with a stopwatch and asked to press the button (of the clock) when the unspeakable act begun and then tap it again when the man experiences his magical moment.
Older men weren't able to last longer than young ones, while wearing a condom or being circumcised didn't boost chaps' performance either.
According to the study, the larger men with more stomach fat and a higher BMI could last for an average of 7.3 minutes in bed.
Interestingly, the research also explores "conventional wisdom regarding penile sensitivity and its relationship to staying power in the sack". Hmm, what do you think?
