“…The term bisexual is difficult to define due to the range of beliefs about what it means to be bisexual. This has been acknowledged by many academics, including Ross et al (2018) and Swan (2018); and a number of authors have written on the topic of defining bisexuality (see, e.g., Barker et al, 2012;Eisner, 2013;Monro, 2015;Ross et al, 2018;Swan, 2018). Used to describe sexual attraction to men and women, the term bisexual is believed to have been first used by the American neurologist Charles Gilbert Chaddock in 1892 (Holleb, 2019), and the term became more widely known and understood after the noteworthy publications of the Kinsey Scale (see, Kinsey, Pomeroy, & Martin, 1948), and the Klein Sexual Orientation Grid (see, Klein, Sepekoff, & Wolf, 1985).…”
