There's no such thing as 'straight' woman

London: Women are either bisexual or gay but "never straight," according to a new research.

Experts from the University of Essex found straight women were strongly aroused by both sexes, even though they said they were only interested in men.

In contrast, lesbians showed far stronger responses to women and barely any when shown the men, the Daily Mail reported.

The researchers said lesbians were the most like men in their responses because it is usually men who show distinct sexual responses to their favourite sex.

Researcher Gerulf Rieger said that even though the majority of women identify as straight, the research clearly demonstrates that when it comes to what turns them on, they are either bisexual or gay, but never straight.

Rieger also said his study showed that lesbians who may dress in a more masculine way may not have more masculine behaviours.

He noted that this shows that how women appear in public does not mean that we know anything about their sexual role preferences.
