Study Shatters 'Bisexual Until Graduation' Myth

A new study may shatter the notion that women who identify as bisexual are "sexually confused" or simply in a "transitional phase" between homosexuality and heterosexuality.

So says lead study author Lisa Diamond, associate professor of psychology and gender studies at the University of Utah. In the small study, which began in 1995, Diamond interviewed 79 women in New York state between the ages of 18 and 25 who identified themselves as lesbian, bisexual or "unlabeled."

Over the course of the next 10 years, she contacted these women by phone to determine, among other things, whether their sexual orientations had changed.

What she found was that while women who identified themselves as bisexual would occasionally waiver on their sexual preference as the years went by, few would ever describe themselves as having switched their preference to become either lesbian or straight. For these women, bisexuality seemed to be a natural state.

The study will be published next week in the January issue of Developmental Psychology, a journal of the American Psychological Association.

Diamond says this finding suggests that bisexuality should not be viewed as a transitional phase in women, but rather should be recognized as a distinct sexual orientation.

"It will hopefully deal a fatal blow to the persistent stereotype that bisexuality 'doesn't really exist,' and that it is simply a phase that women pass through on their way to a lesbian identity," she says.

Other researchers not involved with the study agree that the research brings new information to light.

"It tells us some new things," says J. Michael Bailey, professor of psychology at Northwestern University. "[Diamond] looked at the evidence related to the common assumption that bisexuality is a stepping stone between heterosexuality and homosexuality, and she didn't find evidence to support that in her sample."

Moreover, the study may also debunk the idea that women who identify themselves as bisexual are less likely to be able to commit to a long-term relationship. Diamond points out that at the 10-year follow-up interview, the majority of bisexual women in the study were in monogamous relationships that had lasted at least five years, making them more likely to be in such relationships than their lesbian counterparts.

Even though the study group is relatively small, Diamond says she hopes the relatively long period of time during which the women were studied will quell current notions about the transient nature of female bisexuality.

"If bisexuality really were just a passing phase, then one would certainly expect to see some evidence of that over a 10-year period," she says. "But this study shows that women who reported bisexual patterns of attraction back in 1995 continued to report bisexual patterns of attraction all the way through to 2005, even if they eventually settled down with either a man or woman.

"Hopefully, the media, the general public, and professional psychologists will no longer treat the phenomenon of female bisexuality with skepticism."

Bisexual Women ... but What About Men?

While heterosexuality and homosexuality have historically been presented as clear-cut sexual orientations, bisexuality has always been a somewhat fuzzier issue.

The possibility that an individual could be equally or nearly equally attracted sexually to both men and women gained some degree of support in the mid-1940s, when pioneering sex researcher Alfred Kinsey devised a 7-point scale to measure an individual's sexual orientation. While a rating of zero suggested that an individual was "exclusively heterosexual" and a 6 rating was classified as "exclusively homosexual," the middle numbers on the scale indicated an attraction to both sexes.

Kinsey's scale has since been the target of criticism from some researchers, but it may have helped open a new avenue into the study of the phenomenon, which would become known as bisexuality.

But much about this category of sexual orientation remains mysterious. Only relatively recently have researchers begun to unlock some of the clues to the bisexual puzzle. And one thing they have found is that, for some reason, women may be more likely to describe themselves as being attracted to both sexes.

"Over the years, a number of large-scale representative surveys have suggested that bisexual patterns of attraction are more common among women than among men," Diamond says. "In addition, some laboratory research has suggested that women have more flexible patterns of erotic response to sexual imagery than men."

She says this means women are more likely to be aroused by both same-sex and opposite-sex sexual imagery -- regardless of whether they identify themselves as straight or lesbian -- whereas gay men tend to respond only to same-sex imagery, and heterosexual men tend to respond only to opposite-sex imagery.

Bailey says his previous research corroborates the possibility that the very nature of sexual orientation may be quite different for women than for men.

"Women don't do sexual orientation the same way men do," he says. "It could be that men have evolved to be very specific as to who it is that turns them on, because in particular, the male role has been to go out and find someone that turns them on. Women have evolved differently, for whatever reason, and are more fluid with their sexuality. That's one theory."

But Diamond is quick to point out that just because reports of male bisexuality are sparser does, it does not necessarily mean that male bisexuality is not a myth.

"This is not to say that bisexual men 'don't exist' -- a claim that some researchers have made, but with which I disagree -- but simply to say that we need separate studies of male bisexuality in order to determine its own unique features," she notes.

Changing Perceptions

While the new findings could have an impact in the public's perception of sexual orientation, Diamond says that she hopes her research also has an impact in the professional arena.

"Psychological professionals who encounter such individuals should not prompt them to 'resolve' their attractions in a heterosexual or lesbian direction but should respect the legitimacy and stability of their bisexuality, and help them cope with any stigmatization they may encounter," she says.

Bailey agrees. "I think that it would suggest that counselors should not make the assumption that women who are bisexual are going to eventually decide one way or the other," he says. "There is no reason to think that they would be especially likely to come down on one side or the other."
