A quarter of men aged 18-24 are worried about the amount of porn they are watching on the internet, new research suggests.
Heavy users in the study were much more likely to report problems with their jobs, relationships and sex lives.

They are more worried about themselves, more worried about what they are looking at, and report more relationship problems.
