Bisexuality in women appears to be a distinctive sexual orientation and not an experimental or transitional stage that some women adopt "on their way" to lesbianism, according to new research published by the American Psychological Association.
The study of 79 non-heterosexual women over 10 years found that bisexual women maintained a stable pattern of attraction to both sexes. In addition, the research appears to have debunked the stereotype that bisexual women are uninterested in or unable to commit to long-term monogamous relationships.
"This research provides the first empirical examination of competing assumptions about the nature of bisexuality, both as a sexual identity label and as a pattern of nonexclusive sexual attraction and behavior," wrote University of Utah psychologist Lisa M. Diamond, PhD, who conducted the study. "The findings demonstrate considerable fluidity in bisexual, unlabeled and lesbian women's attractions, behaviors and identities and contribute to researchers' understanding of the complexity of sexual-minority development over the life span."
Diamond used interview data collected five times over a decade from 79 women who identified as lesbian, bisexual or unlabeled. The subjects initially ranged in age from 18 to 25 years old.
Among Diamond's findings:
"This provides further support for the notion that female sexuality is relatively fluid and that the distinction between lesbian and bisexual women is not a rigid one," Diamond wrote.
