Men are notorious for overrating themselves in the bedroom - but now there's a way they can prove they are genuinely superior to others at sex.
A British prophylactic firm has come up with a digital condom that takes data and works out whether or not they're any good at intercourse.
The i.Con Smart Condom, which retails for £60 ($116), claims to be able to measure the velocity of strokes, the calories burned and even the positions used during the latest romp.
It then uses that to judge each user's performance, and ranks them against others from around the globe.
Adam Leverson, lead engineer for the i.Con, described it as a "refined, non-intrusive and lightweight" device.
"There's a lot of tech packed into the i.Con and for us to be able to deliver it in such a way that there is absolutely no hindrance to the user was our main goal," he said.
"I think we have gone above and beyond with the i.Con to make sure of this. I'm just so happy that we can now share the i.Con with the world!"
As well as judging performance, the device can check for potential sexually transmitted infections, lights up, and notes how long each sex session has lasted.
The condom, which nearly 1 million people have expressed interest in, is set for release in January 2018.
