- A growing number of women and men label themselves as bisexual compared with previous years
- It is more common for women to say they are bisexual than lesbian
As awareness about bisexuality has grown over the years, it could be getting easier for people to label themselves as bisexual, said Debby Herbenick, associate professor at Indiana University and author of the book "Sex Made Easy," who was not involved in the study.
Researchers asked more than 9,000 people in the United States age 18 to 44 about the types of sexual experiences they have had, whether they are attracted to the same or opposite sex and whether they identify as being straight, gay/lesbian or bisexual. Interviews were conducted between 2011 and 2013 as part of the CDC's National Survey of Family Growth.
