Good news, bisexual men! A recent study from Northwestern University has confirmed that you do, in fact, exist!
This is countering a previous study by the same research group that suggested men who claimed to be bisexual were really straight or gay. The difference: For this version of the study, researchers made sure to actually recruit some bisexuals.
In the new study, published online in the journal Biological Psychology, the researchers relied on more stringent criteria for selecting participants. To improve their chances of finding men aroused by women as well as men, the researchers recruited subjects from online venues specifically catering to bisexuals.
They also required participants to have had sexual experiences with at least two people of each sex and a romantic relationship of at least three months with at least one person of each sex.
Men in the 2005 study, on the other hand, were recruited through advertisements in gay-oriented and alternative publications and were identified as heterosexual, bisexual or homosexual based on responses to a standard questionnaire.
In both studies, men watched videos of male and female same-sex intimacy while genital sensors monitored their erectile responses. While the first study reported that the bisexuals generally resembled homosexuals in their responses, the new one finds that bisexual men responded to both the male and female videos, while gay and straight men in the study did not.
