Sex is the most intimate form of human contact, a secret, secluded realm. Sexuality, however, the concept which unites body and mind, is becoming an increasingly public subject of concern, as vocal authorities offer varied notions of rights and wrongs. They are profiled here in clear, though dry academic prose. Most pop psychologists say "feeling good" is most important, while the media depict sex as a goal, a symbol of success. (Promiscuity isn't sanctioned in the mass media as much as the New Right might think, though, for Hollywood usually links sex to love, whether for moral or--more likely--dramatic reasons.) TV and film heroes would be pariahs in politics, in turn, for promiscuous leaders are seen as lacking stability, respectability and morality. The authors, both history professors, point out that Gary Hart's demise, swift relative to Richard Nixon's, symbolizes sex's role as a "a symbol capable of arousing deep, irrational fears."
