Every time you purchase a Durex product you add an orgasm for your country to the leaderboard. The more products you buy, the better your country does. You can register your purchase and stand a chance to win a trip for two to Brazil.

You can also add orgasms by doing the 'Sex and Sport Quiz' and sharing it with your friends.

If your country wins 'The Big O' and if you have registered your purchase, you will be entered into the draw to win the trip.
