Usage note

Traditionally bisexual has referred to romantic or sexual attraction to two, and no more than two, genders, specifically male and female. However, the term is increasingly being used to refer to a level of sexual fluidity in which an individual moves bidirectionally along a spectrum of sexuality. This newer sense accounts for attraction to people who do not fall within the gender binary.
