The design of the condom hasn't changed much in 70 years. While this may make it seem like there's no room for improvement, condoms still only offer a 98 per cent success rate. However, things could soon change as sex toy design company Lelo has developed a new type of condom.

This new form of protection - called the Hex - has a unique hexagonal design that has been endorsed by none other than Charlie Sheen. Rather than smooth latex, the Hex has a honeycomb pattern across it, creating a stronger, more pliable condom. Lelo apparently took inspiration from graphene for this design.

According to the company, there are a number of benefits to this type of condom. For starters, the slightly raised structure of the condom helps to reduce slippage during intercourse, resulting in a more snug fit.

The hexagonal elements of the rubber also help the condom to conform to the shape of different penises, improving comfort and safety. It also leads to better sensation during sex because the condom is fairly thin - although not the thinnest on the market.

Possibly the best part of this new design is that it is much less prone to breakages, meaning that panic once the act is over is likely to be reduced. This will help to cut down on unwanted pregnancies and the spread of STIs.

In fact, the condom was shown to be much stronger than traditional variations, as it couldn't be pierced by a pin.

Currently, Lelo is seeking backing through an Indiegogo campaign, which has been so popular that it has smashed its initial goal with a month still to go. It looks like this condom could soon hit the market and become the safer alternative to those that have been available for years.

This could be the biggest breakthrough in condom design since this form of protection became readily available.
