Charles Powell from the USA has invented a new condom and he believes his product is 'easier to use, safer and more secure - and vastly more pleasurable - giving a sex sensation the way nature intended. The secret is the fact that cap device goes on the very tip of the penis to boost sensitivity, Daily Mail reports.

The condom comprises two parts - a U-shape polyurethane adhesive film that wraps around the penis - like a plaster around a finger - and a cap that sticks to it to firmly trap semen. Mr Powell claims the polyurethane part is like a second skin - and can be put on hours or days in advance as it can be worn while urinating and washing.

Mr Powell believes his product provides a solution to three common issues with condoms: a lack of sensitivity, problems getting into the packaging and applying the condom.

When a man wants to have sex, he peels off the paper backing on the cap and sticks it to the polyurethane to securely bond the two and trap semen.

But Jason Warriner, clinical director of the sexual health charity Terence Higgins Trust has criticized the new condoms and said ''It may be suitable for a couple in a long-term relationship but not as a barrier to STIs. This will not prevent the spread of conditions such as HIV or herpes as the whole penis is not covered.

It's estimated that in 2012, 18.5 billion condoms were sold worldwide. This is expected to increase to 27 billion units by next year, with the market worth $6bn.
