What turns us on and where we place ourselves on the sexual spectrum is exceedingly personal. A new study investigating the existence of this spectrum may prove somewhat controversial, then: It claims that women are almost always gay or bisexual and are almost certainly not straight. The research has been accepted for publication in the Journal of Personality and Social Psychology.

Previous studies using volunteers to investigate the sexual arousal of both men and women have been conducted. Many have suggested that women are, on average, physiologically aroused – as in, showing physical changes in their bodies indicating attraction – to both male and female sexual stimuli. The same is apparently not true for lesbians as, surprisingly, they are significantly more aroused by their own sex than by the opposite sex.

This new study, led by Dr. Gerulf Rieger from the Department of Psychology at the University of Essex, asked 345 women of varying sexual orientations to watch a series of videos featuring sexual content. At the same time, their biological responses were measured, including their pupil dilation and their genital response (pulse and blood flow).

The subjects were women ranging in age, educational background, and ethnicity. They were asked to place themselves on a sexual spectrum scale, identifying themselves as either "straight," "mostly straight," "bisexual leaning straight," "bisexual," "bisexual leaning lesbian," "mostly lesbian," or "lesbian."
