A quarter of men are worried about the amount of porn they are watching on the internet with lower monthly download limits and higher quality, and therefore size, of the videos available being the main areas of concern.
'I used to be able to get as many videos as I wanted', explained Jim from Leicester, 'The way things are going I'll struggle to get a handful.'
Although men appear to be the most effected by this issue some members of the other half of the species also have their worries.
'Porn is his backup if the World of Warcraft servers ever go down,' explained Lula Baines of Wimbledon, 'without that option he is likely to start attempting to have sex with me again and he's almost certainly going to notice I left him four months ago, taking all his worldly belongings and emptying the bank account as I left. I imagine he'll also notice that no one has been feeding the cat.'
Emergency porn 'walk in' centres are being considered by some local councils but as yet have not passed the casting couch stage.
