Report: Sexuality less varied in women
While the official cause of human sexuality remains debatable, one Michigan State University scientist has said women typically are more sexually flexible.
Neuroscientist Marc Breedlove told The New York Times that his research has found that men typically maintain an attraction to one specific gender, while women tend to be more flexible regarding their sexuality.

"Most males are quite stubborn in their ideas about which sex they want to pursue, while women seem more flexible," Breedlove said.

The neuroscientist added that the prevailing approach to sexuality in the scientific community appears to support the formation of male sexuality before birth.

"I think most of the scientists working on these questions are convinced that the antecedents of sexual orientation in males are happening early in life, probably before birth," Breedlove told the Times, "whereas for females, some are probably born to become gay, but clearly some get there quite late in life."
