Although most researchers would agree that both women and men might define themselves as bisexuals or behave bisexually, whether men can be sexually aroused by both sexes, that is, have a bisexual orientation, was contested.
Reflecting how science should work, members of the bisexual arousal naysayers joined with a group of bisexual arousal proponents to put the matter to the test. Results were just published in the prestigious journal, Proceedings of the National Academy of Sciences, with the following conclusion:
“This controversy can be resolved using objective, genital responses of men to male and female erotic stimuli. We combined nearly all available data (from eight previous American, British, and Canadian studies) to form a dataset of more than 500 men, much larger than any previous individual study, and conducted rigorous statistical tests. Results provided compelling evidence that bisexual-identified men tend to show bisexual genital and subjective arousal patterns. Male sexual orientation is expressed on a continuum rather than dichotomously.”
With these results, the researchers joined the millions of men and women who know they have a bisexual orientation, a perspective endorsed by nearly every bisexual group, organization, website, and social media outlet.
