I've found out that my teenage son, who's 17, has been looking at pornography online. However, it's not Playboy or anything like that, not even women for that matter, but pictures of Wes Scantlin (look him up on Google). I only knew about it having found a print-out with a picture of Wes and stained underpants whilst cleaning the house. I also found hundreds of magazines with pictures of Wes Scantlin in them - as well as newspaper cuttings too.
In an attempt to try and break him from this addiction, I cooked his favourite meal for tea, but he ignored me and went straight to the computer, masturbating over pictures of Wes Scantlin. He's even started dressing up like him otside of school - and I worry for him. He comes in from school, makes himself something to eat, and then sits masturbating over pictures of Wes. He doesn't show this level of interest over other men, indeed, it only seems to be Wes Scantlin he's interested in. He even ignores homework/schoolwork just to look at pictures of him.
Now he just won't stop looking at the pictures. I've tried talking to him about the issue calmly, but he just refuses to discuss the issue, claiming I'm intruding on his personal life. He'll discuss any issue but this one. My husband is concerned, worrying about this, and I'm sure my son's girlfriend will be if she finds out about this.
How should we deal with this?
