Being a sex addict is in my jeans. Duh, I knew that! Oh, those genes.

Some people simply can't help being 'sex addicts', according to a new discovery by scientists.

They have found that people with a certain genetic make-up have a much stronger sex drive than others.

The remarkable finding could go some way to explaining the behaviour of self-confessed 'sex addicts' such as Michael Douglas.

Lead researcher Professor Richard Ebstein of Hebrew University said the study is the first to identify a specific gene variation linked to sex drive.

"Some people really do think more about sex and place a greater importance on it than others and what our study suggests is that genes may make a substantial contribution to these differences," he said.

Wait, are people saying this is a bad thing?

Trust me there are worse things to be addicted to.
