When I was a junior or senior in high school at Trinity in New York, Paul Krassner published an interview with Norman Mailer in The Realist in which Mailer stated that he thought masturbation had the effect of muting or blunting or otherwise desensitizing one’s sexual compass, so to put it. I thought this was interesting and provocative, although it fell short of exerting a strong influence on my own habit. Still, I admired Mailer, and if I couldn’t emulate him I did read him with sincere interest, especially Advertisements for Myself, which contained his heralded sequence “The Time of Her Time,” comprising fifty pages about Sergius O’Shaugnessy’s efforts to give his Jewish girlfriend an orgasm.
