The present paper investigates the (non-)representation of non-monosexualities, an umbrella term covering bisexualities, pansexualities, sexual curiosities, fluidities, and other forms of non-monosexual queerness, in contemporary British and US-American culture. It will be argued that both the heteronormative mainstream and LGBT+ culture are complicit in the spatio-discursive exclusion of non-monosexualities by denying the latter access to a valid identity category. Additionally, this paper seeks to illustrate that non-mononormative sexual identities show themselves to be anti-complicit in the maintenance of their epistemic erasure. This non-complicity manifests itself culturally and linguistically. More and more young adults define themselves as neither completely heterosexual nor completely homosexual, thereby positioning themselves on a spectrum rather than within rigid categories. Linguistically, there has been a recent surge of new terms to describe one’s sexuality that defy both the gender binary and the inalterability of one’s sexual orientation, such as pansexuality and heteroflexibility/homoflexibility. By questioning the heterosexual/homosexual binary a new binary opposition is created: bisexualities, pansexualities, pluralities, fluidities, and polarities are juxtaposed with mono-categories. The analysis is rounded off with the suggestion to incorporate hitherto largely undertheorised identity categories such as non-monosexualities into intersectional analyses and the exploration of normalizing processes.
