Women are three times more likely to be bisexual than men, study says

Women's sexuality is more "adaptive" than men's, psychologists have found. They are more likely to become bisexual if opportunities arise to explore same-sex relationships, say researchers.

Men, on the other hand, are more likely to stay on one side of the sexual fence.

Scientists from the University of Notre Dame in Indiana tracked 5,018 women and 4,191 men as they progressed from adolescence to young adulthood.
