Pornography study that was doomed to fail after scientists couldn't find a single man who hadn't viewed X-rated material



Single men watch X-rated material on average three times a week



Scientists studying the effects of pornography fell at the first hurdle - after failing to find a man who had not viewed X-rated material.

The researchers were comparing the views of men in their 20s who had never been exposed to pornography to regular users.

But Professor Simon Louis Lajeunesse, of Montreal University in Canada, said: 'We started our research seeking men who had never consumed pornography. We couldn't find any.'

Although hampered in its original aim, the study was then changed to examine the habits of men who regularly used porn.

It found single young men viewed such material on average for 40 minutes three times a week, compared with those in relationships, who watched it 1.7 times a week for 20 minutes.



And it revealed 90 per cent of porn is taken from the internet and 10 per cent from video shops.

Boys first watched pornography when they were just ten years old, the study also found.
