Do you often watch mucky videos but find the action is a bit, well, flat? Never fear, we're giving away four copies of 3D Sex & Zen: Extreme Ecstasy so you can leap right into the action in 2012...

In case you've never heard of 3D Sex & Zen: Extreme Ecstasy, it's the erotic action epic that is breaking box office records all over the world:

"An adaptation of the classic novel The Carnal Prayer Mat, the film follows a young Ming Dynasty scholar named Wei Yangsheng on an eye-opening journey of sexual discovery. The film is "The World's First 3-D Erotic Film". In Hong Kong the film beat the opening days grosses of Avatar and Titanic with an opening day gross of $351,000."

So to sum up; Ming Dynasty, sexual discovery, beat Avatar's opening day grossing.

Instead of the new 3D technology you might have seen dads queuing up to have a go on in flashy showrooms, it uses those old red/blue glasses, meaning you can watch the DVD anywhere. Even your little old bedroom telly. In the dark.

For your chance to win one of the four copies, simply submit the answer to the following question in the box below by 28th Dec.
