I saw this today on the Rolling Stone blog.
Anthony Keidis, a recovered heroin addict said this,
“When I finally got a computer, I discovered this limitless world of pornography.
“I realised the same feeling I was having was the same I used to get when scoring drugs. Sex can have a dark side.
“I actually had to make a commitment to myself to stop.”link to original
I offer no commentary. However, this is a frightening thought.
