A high-tech sex toy has been created to track activity via a smartphone.
The one-size-fits-all gadget keeps an eye on your top speed, number of thrusts, and calories burned during saucy sessions.
Named 'Lovely', it has built-in Bluetooth and uses the data to recommend 120 different positions.
It is designed to fit onto a man's member, but also vibrates and has a battery which lasts around seven hours.
In a promotional video, Reid Mahalko, a sex and relationship expert, said: "It doesn't just have to go on a penis.
"You can put it on your fingers, you can use it on a toy on yourself."
