I’ve asked this question a thousand times. This article from examiner.com gives you an idea of how difficult it is to arrive at a consensus. I personally believe, as far as men are concerned, if we could take the entire male population and strip away a lifetime of indoctrination, if men were allowed to perceive and react to what comes natural to them, the numbers would be astounding.

No wonder we bisexuals feel so alone–we don’t even know how many of us exist. Estimates range from zero to tens of millions in the United States alone, depending on which study you believe.
It’s not easy to find hard numbers on this. To quote scholar and activist Loraine Hutchins:
Newer Kinsey Institute studies found both more evidence of bisexuality, and more denial. A late 80s study, for instance, showed 46 percent of (self-labeled) lesbians, not bisexuals, reporting having sex with men since in the ’80s”
Time Magazine said any statistic is unreliable because people who engage in such behavior don’t consider themselves bisexual.
Here are other reports:
* 0.3% of women and 0.7% of men engaged in sexual activity with both males and females within the previous year-”Sex in America,” University of Chicago, 1992
* 1.5% of women and 0% of men defined as bisexual based on sexual and romantic attraction-National Institutes of Health, 2002
* 5% of women and 10% of men fall solidly into a middle level of the Kinsey scale of sexual preferences. However, when accounting for people’s actions and attractions, as many as 25% of women and 46% of men could be labeled as bisexual.-Dr. Wardell Pomeroy, director of field research for The Institute for Sex Research
