When it comes to sexuality, women are more flexible!

London, May 17: If you are a girl and like to have sex with your male partner one day and a female pal the next, you may not be alone. A new theory suggests that women may have been evolutiorily designed to be sexually fluid. “The theory suggests that women may not have sexual orientations in the same sense as men do,” said Satoshi Kazawa, reader in London School of Economics and Political Science. “Rather than being straight or gay, to whom women are sexually attracted may depend largely on the particular partner, their reproductive status, and other circumstances,” Kazawa said. Kazawa proposed the theory in an article published in the jourl Biological Reviews. The theory explains why women can change their sexual desires and identities from lesbian, to bisexual, to heterosexual and back again, according to Kazawa. Female sexual fluidity may have evolved as an adaptation to facilitate polygynous marriages, in which a husband can have more than one wife. In evolutiory terms, sexual fluidity allowed them to have sex with their co-wives in polygynous marriages, therefore, reducing conflict and tension inherent in such marriages while at the same time successfully reproducing with their husbands in heterosexual unions, the research said. The theory may also help explain why men enjoy watching lesbian sex, and a number of puzzles in human sex research, including differences in female and male homosexuality, and menstrual synchrony.
