Here's a condom that can rate performance

The makers of the world’s first smart condom have finally revealed how the device will look like. It boasts the ability to detect STIs, assess performance and even calculate how much calories a person burned while having sex.

The i.Con Smart Condom is a ring shaped wearable that mimics another popular sex toy that sit at the base of the penis. It is priced at $80.

While there are potential benefits, the smartphone-connected device has sparked concerns that it could be used to spy on a person’s intimate moments.

The i.Con it turns out can be used in conjunction with a real condom and is lightweight and water resistant. It has a nano-chip and Bluetooth capabilities built in and can provide a range of statistics to help improve the wearer’s sex life.

This includes duration, speed, and girth measurements.

The device also records the amount of calories burned, different positions, and can detect chlamydia and syphilis.

All information will be kept anonymous - but users 'will have the option to share their recent data with friends, or, indeed the world.'

The firm claims 90,000 people have already pre-ordered the product which will be released later this year at the price of £59.99 ($80.99).
