At a still more physical invariable it is also 20 years since I enrolled as a PhD evaluator, researching the iconography of gay porn, funded by the British Arts and Humanities Explore Trustees and inspired by the work of scholars such as Waugh and Dyer (1985, 2002). This was the locale at which my academic craft decently began and a probing track was plotted that has led to the publication, this year, of my own paper, Gay Filth: Representations of Sexuality and Masculinity (Mercer 2016). Porn matters as a cultural exception, and it first matters to gay men. It mattered in the 1960s when Joe Dallesandro appeared bare in the pages of On Pictorial, Gay0Day it mattered in the 1980s enough for Waugh to urge a case destined for its investigation, it mattered in the 1990s in the middle of the AIDS crisis and it matters now.
