The book "On Being a Prostitute" (Perkins & Bennett, 1985) is a valuable contribution to the sociology of deviance and sexual ideologies. However, comprehensive as it is, the book presents certain omissions and flaws, with implications for both is empirical data and theoretical underpinnings. In focusing on male (homoerotic) prostitution, and drawing upon Bennett's (1983) "Twenty-Ten" survey (which forms the main empirical base of that aspect of the book), I argue that certain categories of male prostitutes have been excluded. These omissions, I suggest, were necessary to allow Bennett's hypothesis that most male prostitution derives from economic necessity--a recurrent economic determinism reminiscent of Havelock Ellis (1906/1936), and somewhat contrary to a broader structural approach (see Mathews, 1983).
