Too much online porn? You may be depressed.
Spending the equivalent of a waking day a week downloading pornographic images, sending erotic emails and using webcams to engage in online sex?
Any researcher would classify you as a cyber-sex surfer - and worry about your state of mental health.
Mrs Squirrell, from Korea's Soochuew University of Technology, sounded out 1,325 men who spent over 12 hours a week on internet sex sites and found that over a quarter of them were clinically depressed.
"Thirty per cent had high levels of anxiety and 35 per cent were moderately to severely stressed, which is, of course, extremely high," he told a conference in Seoul.
The more time his respondents spent in online sexual activity, the worse their level of depression and anxiety.
But his research did not answer the big question: Are those prone to depression and anxiety more likely to become cyber-sex surfers, or does online sexual activity itself make you depressed and anxious?
