Originally published in 1975, The Fantasy Factor documents the ‘ubiquitous influence’ of sexual fantasy on human behaviour.

Delving into questions surrounding risk, intimacy, social norms and deviancy, Dally considers the established and classic psychology surrounding sex. He also sheds light on the way this psychology exists alongside an increasingly voyeuristic and liberal society which attempts to reconcile sexual fantasy with aspirations of faithfulness and marital norms.

Through case studies and observations, he asks whether sadism and machoism exist more frequently than we admit, and explores how sexual fantasy finds expression in work and daily life. In considering the effects of sexual fantasies on people’s lives, he questions whether fantasies can be gratified and indeed whether they should they be gratified. Is sexual fantasy a power that can be harnessed or a disorder that should be treated?

From marriage, pornography and witch-hunting, The Fantasy Factor examines the lure of sexual fantasy that has been a constant throughout history.
