I welcome a statement on the term 'sex addiction' from the Sexual and Relationship Therapy journal. They argue that concept of "sex/porn addiction" should not be used because it is not evidence-based and not endorsed scientifically. 

The term 'sex addiction’ presupposes that there exists a norm of healthy sexuality from which the patient deviates quantitatively. The problem is not 'too much sex' but the patient’s relation to their own enjoyment - their attempt to plug a lack. Instead of a moralizing discourse of addiction, control and abstinence, we might speak of the failure of desire.
