Heterosexual pornography, predominantly produced by and for men, concerns itself almost exclusively with what the sociologist Anthony Giddens calls “low emotion, high intensity sex.” In part, it meets the needs of many men to compartmentalize their sexual and emotional lives, and to separate their secure relationships from their rash urges. But it also serves an additional purpose not immediately apparent. While opponents of porn focus primarily on the aggression and violence of male sexuality, Giddens makes the point that the male potency displayed in these stories is a manifest reassurance against male insecurities—sexual and other. The female characters in much pornography (themselves invulnerable) neutralize male vulnerability because they are always fully responsive and fully satisfied. The man never suffers from inadequacy, because the woman is in a state of ecstatic bliss that is entirely his doing. She confirms his virility.
