In 1922, the term 'monosexual' was used by psychoanalysts. It was elaborated upon by Wilhelm Stekel, who believed that individuals only behaved as if they were monosexual, but that no one was actually monosexual.[3] However, the anthology Bi Any Other Name stated that the term was created by the bisexual movement.[4]

The mono- pride flags were created by Tumblr user beyond-mogai-pride-flags on January 16, 2018.[5]

Content Warning: Monosexism
Monosexism is the belief that human beings should or can only be attracted to (and have relations) with a single gender. Monosexist individuals may see bisexual/biromantic individuals as promiscuos, greedy, indecisive, confused, going through a phase, more likely to cheat on their lover, sinful, and more.[6]
