Where's the harm? What's the problem? That's what you'll be thinking if you are not a man whose relationships have crumbled because of your compulsion for internet pornography, or a man who has lost his job because his compulsion has led him deeper into illegal areas such as child porn, or if you are not a man who has had to call in the computer doctor to clean up your hard drive when the websites you are viewing have become violent, or if you are not a man whose habit has led him to seek therapy for sex addiction. If you are one of these men, you will know that there is a continuum here that can lead from thoughtless gratification to fear, shame and misery.
