A brand new sex device will measure how good you are in bed - and then let you 'brag' by sending your data to friends.

The 'smart condom ring', set to go on sale next year, will measure details including the number and speed of thrusts, how long intercourse lasts and what positions the wearer has sex in.

Girth measurement, calories burned and frequency of intercourse will also be recorded - giving buyers a full picture of their sexual prowess.

But it doesn't end there.

The device, designed by Nottinghamshire firm British Condoms, will also allow people to upload their stats to as few or as many people as they want using nano-chip and bluetooth technology.

It will also be able to detect sexually transmitted infections such as chlamydia and syphilis, the Nottingham Post reports.

The £60 i.Con Smart Condom ring will allow users to relay data to a smartphone app.

The company says that all data will be kept anonymous - but users "will have the option to share their recent data with friends, or, indeed the world".

The ring is worn at the base of the condom, is adjustable for size, and can be worn again and again.

It has an integrated micro USB port so it can be recharged, with each charge lasting about six to eight hours.

British Condoms worked with a lead engineer from Durham University to help develop the prototype rings.

The ring has an antibodies filter, and when proteins or antigens which are found in STIs are detected it will send an alert to the smartphone app.

Adam Leverson, lead engineer on the i.Con project, said: "Not only have we innovated the world's first smart condom ring - that'll measure pretty much every aspect of performance in the bedroom - but now I'm pleased to confirm that it will also have built-in indicators to alert the users to any potential STIs present."

Aaron Slater, spokesperson for British Condoms, added: "We knew we were on the cusp of creating something special with i.Con, and bringing a new meaning to 'wearable tech' - but being advocates of safe sex, we wanted something more, and the addition of an STI indicator has certainly done that."

The i.Con is currently in final stages of testing before its release in January 2018.
