“Is pornography addiction real?” I have frequently asked this question myself while scouring the vast literature on pornography. Throughout my reading, I have observed that despite pornography research being conducted for much of the last half-century, it still says little with any certainty about how pornography and its audience interact. Indeed, as I will discuss in this chapter, a question as to pornography addiction’s ‘realness’ is undercut by the fact that pornography addiction remains unrecognised ‘officially’ as a discrete diagnosis or disorder (it remains absent as a diagnosis in the fifth edition of the Diagnostic and Statistical Manual of the American Psychiatric Association or the subsequent revision of the International Classification of Diseases). At the same time, however, comparisons between the ‘official’ status of pornography addiction and media coverage espousing the addictiveness of pornography show that pornography addiction’s ‘realness’ arises irrespective of—or perhaps because of—elusive empirical conclusions about pornography viewing. Pornography addiction has its own social life, not bounded by strictures of academic theorising or clinical operationalisation. Thus, as I will explore, pornography addiction operates in a peculiar space, as an informal yet seemingly popular self-diagnosis, not officially recognised by researchers or mental health diagnostic bodies, as well as a familiar way to describe pornography viewing/viewers.
