A survey by The National Center for Health Statistics has revealed women in the US are far more likely to say they are bisexual compared to men.
The National Survey of Family Growth survey asked 9,100 adults aged between 18 and 44 about their sexual identity and sex life.
According to the results covering 2011 to 2013, 5.5% of female respondents said that they identified as bisexual, compared to only 2% of male respondents.
The survey was conducted anonymously via computer rather than directly through a person-to-person interview.
In the previous 2006 to 2010 survey 3.9% of female respondents identified as bisexual compared to only 1.2% of male respondents.
There was no significant change in the percentage of respondents who identified as homosexual or heterosexual.
This mirrors findings in similar studies that have been conducted around the world.
A study conducted by the University of Notre Dame in the United States also found the women were three times more likely to identify as bisexual.
Also, data that was released last year rom the UK’s Office for National Statistics found that women were twice as likely to identify themselves as bisexual when compared to men.
According to Dr Elizabeth McClintock, an assistant professor of sociology at the University of Notre Dame in the United States, these results show that female sexuality may be more adaptive and flexible and male sexuality.
Women with some degree of attraction to both males and females might not be drawn into heterosexuality if they have favourable options in the heterosexual partner market.
Women who are initially successful in partnering with men, as is more traditionally expected, may never explore their attraction to other women.
However, women with the same sexual attractions, but less favourable heterosexual options might have greater opportunity to experiment with same-sex partners.”
