According to a study conducted by Dr. Gerulf Rieger from the Department of Psychology at the University of Essex, most women are never straight. They are either gay or bisexual.

According to a report in the Independent, the study involved 235 women who were shown videos of naked men and women and their responses were recorded.

Although lesbians are attracted to females, 74 per cent women in  the test who said they are straight were attracted to videos of both naked men and women.

As per the study, 82 per cent of the women were aroused by both sexes, based on indicators such as whether their pupils dilated in response to sexual stimuli.

In contrast, lesbians showed much stronger sexual responses to women than to men.

“Even though the majority of women identify as straight, our research clearly demonstrates that when it comes to what turns them on, they are either bisexual or gay, but never straight,” Dr Riegler said.

He also said the study showed lesbians who may dress in a more masculine manner may not have more masculine behaviours.

The study shows us that how women appear in public does not mean that we know anything about their sexual role preferences.

It also found 41 per cent of people identify themselves as somewhere between homosexual and exclusively heterosexual – suggesting people are increasingly seeing sexuality in a less polarised manner.
