Psychologists during the 1960s were especially drawn to the significance of the long hair preferred by the Beatles and the bands that emerged soon after their breakthrough. Academics proposed that the long hair signalled androgyny and thus presented a less threatening version of male sexuality to teenage girls, as well as allowing male fans to view the group in a sexual regard that they normally reserved for young females. Other concerns related to the Beatles' own sexuality; whether the haircuts were a projection of latent homosexuality or confident heterosexuality. In their 1986 book "Re-making Love: The Feminization of Sex", authors Barbara Ehrenreich, Elizabeth Hess and Gloria Jacobs argued that the band's presentable suits meant that they seemed less "sleazy" than Presley to middle-class whites.
