A recent study in the Journal of Personality and Social Psychology has found that straight people don’t exist. The researchers aren’t concluding that everyone is homosexual either. It’s actually complicated, just like the study showed our sexual arousal to be.

The study “challenges the heteronormative values long held by Western society,” and found that women are aroused by both straight and gay adult entertainment.

Ritch C. Savin-Williams, the Director of Developmental Psychology and the Director of the Sex and Gender Lab in the Department of Human Development at Cornell University conducted the study as “part of a much larger research project he and his fellow researchers are doing to uncover true human sexuality through physiological queues.”

The researchers ran the study on women and found regardless of what orientation they reported to be, they had the same neurological reactions to depictions of both hetero- and homosexual activities.

Savin-Williams said of the research project:

“It’s basically a study that assesses sexual orientation by looking at the eyes and whether they dilate or not. You can’t control your eye dilation. Essentially, that’s what the whole project attempts to get at, another way of assessing sexuality without relying on self-report. Another way, of course, is genital arousal, but that gets a little invasive.”

Here’s where it gets tricky. Following popular and traditional logic on sexuality, humans are thought to be either straight or gay. Bisexuality has only recently gained acceptance in society through the help of LGBTQ groups.
