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, says researchers.Men, on the other hand, are more likely to stay on one side of the sexual fence or the other.
US scientists tracked 5,018 women and 4,191 men as they progressed from adolescence to young adulthood, questioning them about their sexual activity.
They found that women were three times more likely than men to change their sexual identities.
Women who were more educated, more physically attractive, and who avoided young motherhood were less likely to experiment with bisexuality.
