A British company has released the first pictures of a ‘smart condom’ which collects very intimate data about the sex life of anyone brave enough to wear it.

The device is called the i.Con and can detect STIs as well as sending data about a sex session straight to the wearer’s smartphone, reports the Metro.

British Condoms said its ‘revolutionary wearable tech for the bedroom’ measures the number of calories burned during intercourse, the speed of a man’s thrusts, how long he lasts and even what positions are used.

The condom firm said its invention would help men see how they ‘stack up to other people from around the world’.

However, it’s far from clear whether lovers will be happy with the idea of letting a condom spy on their most private moments.

Adam Leverson, lead engineer for the i.Con Smart Condom, said: ‘It’s here and it’s beautiful. We wanted the i.Con to look refined, non-intrusive and lightweight – the finished article is nothing short of any of those things.

‘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 – and 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!” The smart condom is a small band which fits around the bottom of a man’s willy, which means wearers will still need to strap on a normal condom to get full protection.

It is waterproof and features a band that’s ‘extraordinarily flexible to ensure maximum comfort for all sizes’.

Bizarrely, it even lights up to provide illumination for both partners’ nether regions.

John Simmons, a spokesperson for British Condoms, added: ‘We’re extremely excited to share with the world the first glimpse of the i.Con Smart Condom Ring due to go on sale in the UK in January 2018.

‘It’s truly the next step in wearable tech and we believe we have pioneered a product that will not only bring an extra element of fun into the bedroom, but will also help indicate potential STI’s present as well as prevent condom slippage, a leading cause of unplanned pregnancy in the UK.’

The condom company claimed 900,000 people have already written to express interest in the gadget.
