More American men and women are identifying as bisexual, reports a recent publication by the Centers for Disease Control and Prevention.

The study, which utilised the data collected from the 2011-2013 National Survey of Family Growth (NSFG), aims to provide ‘national estimates of sexual behaviours, sexual attraction, and sexual orientation among women and men aged 18–44 in the United States.’

Over 9,000 adults’ interview results were used to churn out the end statistics.

The outcome reports that 5.5% of women and 2.0% of men said they are bisexual in the 2011–2013 NSFG, as compared to the previous 2006–2010 NSFG study which found that only 3.9% of women and 1.2% of men identified as bisexual.

And among those who reported themselves as ‘heterosexual or straight,’ 12.6% of women and 2.8% of men said that they had had same-sex sexual contact.

The study also provides other interesting insights about what different couples do in bed:

Women who reported to be ‘homosexual or bisexual’ were more likely to have had anal sex with an opposite-sex partner (44.2%) compared with 35.4% of heterosexual women.

More women in the ‘homosexual or bisexual’ group had ever had opposite-sex sexual contact (89.7%), as compared to men (67.9%).

And surprisingly, or not, 16.4% of women and 11.4% of men who had identified as ‘homosexual or bisexual’ had never had same-sex sexual contact.
