All-male SEM represents 33–50% of the market ( Morrison, Morrison, & Bradley, 2007), though only 3.9% of the US male population are estimated to have had sex with men in the last five years ( Purcell et al., 2012). Both nationally and globally, it has been estimated that 86–98% of men have ever viewed SEM ( Carroll et al., 2008 Haggstrom-Nordin, Hanson, & Tyden, 2005 Hald, 2006). For example, in 1970, the industry’s annual revenue was estimated to be between $5 million and $10 million in 2006, this estimate had grown to $13 billion, representing a 1300% increase in revenue ( Carroll et al., 2008 Egan, 2000). In the United States, the consumption of sexually explicit media (SEM) has grown exponentially as advances in technology have made it accessible, affordable, and anonymous ( Cooper, Delmonico, & Burg, 2000 Egan, 2000).
