The new condoms were a hit with testers.
Scientists have invented a condom that they hope will make safe sex more appealing.
Researchers in the US, backed by the Bill and Melinda Gates Foundation, have designed self-lubricating latex condoms that become slippery on contact.
They hope they will be the answer in helping promote safe sex and preventing sexual transmitted infections and unwanted pregnancies.
The self-lubricating condom is less likely to break or cause discomfort than regular condoms thanks to a special, durable coating.
The research, published in the Royal Society Open Science journal, say it can withstand 1,000 thrusts without losing its slipperiness.
Boston University's professor Mark Grinstaff said:
"It feels a bit slimy when you handle it dry, but in the presence of water or natural fluids it becomes really slick. You only need a little bit of fluid to activate it."
A group of volunteers were given the new self-lubricating condoms and also regular condoms coated with a shop-bought, water-based liquid lubricant.
They were asked to touch and rate them in terms of slip and slide.
73 per cent of the participants rated the self-lubricating condom more highly.
It's believed clinical trials with couples could begin early next year.
