Some solid points raised by Mr B - the reality of 'porn addiction' and 'sex addiction' is subject to extensive debate amongst psychology academics and counsellors. Such terms may become accepted in the next edition of the DSM (the manual of mental disorders followed US psychologists and clinicians) or they may remain unrecognised. The debate goes on...
It's true that the concept has also been hijacked by moralising religious groups and commercial "sexperts". Candeo is an expensive porn addiction recovery product sold by members of the LDS church. So I'll leave you to make your own conclusions about that
In reality, a problem relationship with porn is indicative of deeper emotional issues. Depression, low self-esteem, emotional isolation, acute stress; you name it, porn provides mind-numbing distraction and avoidance. Internet porn is also anonymous, endless and free. A heady mix indeed, and a trap that anyone can find themselves falling into.
There are some excellent help resources for people struggling with compulsive porn use, and speaking to a qualified therapist is highly recommended. There are many fans of the 12 step approach, but I share Mr B's reservations.
But whatever we decide to call it, many sane and intelligent people are finding it difficult to stop spending too much time oggling porn. The good news is that with a little therapy and perspective, they can learn to meet their emotional needs in more positive, fulfilling ways.
