For those who missed it at the weekend - Britain is the world's fastest growing market for internet pornography. You should all be very ashamed.

British women are the fastest growing group of users with a 30 per cent increase on last year - up to 1.4m from just over one million last year. One in four men aged between 25 and 49 has visited an adult site in the last month - about 2.5m people.

The survey comes from Neilsen Netratings and was commissioned by the Independent on Sunday - more details here.

But not everyone is impressed.

Agencies like Relate report that 40 per cent of couples asking for relationship help cite internet pornography as a contributory factor to their problems.

Phillip Hodson, of the British Association for Counselling and Pyschotherapy, told the Independent it was making "sex-lazy men even sex-lazier". He said: "It used to be said that men neglected foreplay, but now they are neglecting sex."®
