Where Does the “B” Belong?: Anti-Bisexual Experiences, Self-Stigma, and Bisexual Individuals’ Sense of Belonging

Abstract Bisexuality remains a stereotyped sexual identity in which bisexuals face prejudice from both gay/lesbian and heterosexual populations. Some bisexual individuals internalize society’s negative attitudes, resulting in an experience of self-stigma. Consequently, many bisexual individuals report a reduced sense of belonging. The current study explored whether self-stigma mediates the association between experiences of anti-bisexual prejudice and a sense of belonging within a bisexual sample (n = 529) while also identifying how experiences of anti-bisexual prejudice vary as a function of participant gender (man, woman, non-binary) and the source of prejudice (gay/lesbian or heterosexual). Self-stigma fully mediated the association between anti-bisexual experiences and a sense of belonging. Women and non-binary individuals reported more frequent anti-bisexual experiences than men, and all participants reported more frequent anti-bisexual experiences from heterosexual versus gay/lesbian sources. Efforts to improve a sense of belonging among bisexual individuals should focus on reducing anti-bisexual prejudice and anti-bisexual self-stigma.
