board meeting, where members would decide which studies to fund and also brainstorm ways to increase bisexual visibility “in a world that still isn’t convinced that bisexuality - particularly male bisexuality - exists,” as Allen Rosenthal, a sex researcher at Northwestern University, told me. I was sandwiched in the back seat of the car between John Sylla and Denise Penn, two board members of the Los Angeles-based American Institute of Bisexuality (A.I.B.), a deep-pocketed group partly responsible for a surge of academic and scientific research across the country about bisexuality. We were headed south from Los Angeles to San Diego on an overcast morning last spring, but we hadn’t moved in 10 minutes. The traffic was bad, even by the warped standards of a Southern California commute.
