A growing number of people in the UK identify as bisexual, pansexual or 'not per cent heterosexual'. Women are more likely to be sexually fluid than men because evolution historically required them to have sex with co-wives in polygynous marriages, an evolutionary biologist has claimed. Many more women than men say that they experience same-sex attraction or have had a sexual experience with someone of the same gender.

When it comes to sexual behaviour in vertebrates, the two sexes are more alike than different. Yet whilst their bodies are usually male or female, their brains are bisexual and intrinsically capable of behaving as either sex. Most animals begin their lives as a single cell, grow and develop into one of two sexes and, when mature, interact with the other sex to conceive a new single cell that starts the cycle anew.

Women may be more "hetero-flexible," or be primarily attracted to men with some same sex attraction, because same-sex behavior allowed women to raise their children with other women, a new study has proposed. The hypothesis, published this April in the journal Evolutionary Psychology, suggests that more fluid female sexuality may have evolved because it benefited women's offspring. Some women who were raped or fathered children with absentee or deceased dads formed sexual relationships with other women, which may have made it easier to raise children together, according to the theory.

Bisexuality is romantic attraction, sexual attractionor sexual behavior toward both males and females, [1] [2] [3] or to more than one sex or gender. The term bisexuality is mainly used in the context of human attraction to denote romantic or sexual feelings toward both men and women, [1] [2] [3] and the concept is one of the three main classifications of sexual orientation along with heterosexuality and homosexualityall of which exist on the heterosexual—homosexual continuum.

Women are scientifically found to be aroused by erotic situations involving both males and females, and while that may not be entirely indicative of inherent bisexualism, since being aroused doesn't necessarily mean one wants to partake in sexual actionit would make sense in terms of evolution. Women have a lesser sex drive since they are the bearer of the children, so they would, in history, partake in same-sex activity. There's also a very apparent trend between women's changing sexual identity with age.
