If the homosexual-heterosexual range is a continuum, individuals at the midpoint should be characterized by equal frequency, equal pleasure, and relatively random sex choice of their partners. A small sample of bisexuals, self-identified according to these criteria, was interviewed. If these individuals are typical, sexual choice is dichotomous, rather than continuous, and inferences based on a continuum are untenable.
