Denial and erasure Biphobia can lead people to deny that bisexuality is real, asserting that people who
identify as bisexual are not
genuinely bisexual, or that the phenomenon is far less common than they claim. One form of this denial is based on the
heterosexist view that heterosexuality is the only true or natural sexual orientation. Thus anything that deviates from that is instead either a psychological pathology or an example of anti-social behavior. Another form of denial stems from
binary views of sexuality: that people are assumed
monosexual, i.e. homosexual (
gay/
lesbian) or heterosexual (
straight). Throughout the 1980s, modern research on sexuality was dominated by the idea that heterosexuality and homosexuality were the only legitimate orientations, dismissing bisexuality as "secondary homosexuality". In that model, bisexuals are presumed to be either
closeted lesbian/gay people wishing to appear heterosexual, or individuals (of "either" orientation) experimenting with sexuality outside of their "normal" interest.
Maxims such as "people are either gay, straight, or lying" embody this
dichotomous view of sexual orientation. Thus the many bisexual individuals with unequal attractions are instead categorized as either homosexual or heterosexual. Others acknowledge the existence of bisexuality in women, but deny that men can be bisexual. Some denial asserts that bisexual behavior or identity is merely a social trend – as exemplified by "
bisexual chic" or
gender bending – and not an intrinsic personality trait. Same-gender sexual activity is dismissed as merely a substitute for sex with members of the opposite sex, or as a more accessible source of
sexual gratification.
Situational homosexuality in
sex-segregated environments is presented as an example of this behavior. Biphobia is common from the heterosexual community, but is frequently exhibited by gay and lesbian people as well, usually with the notion that bisexuals are able to escape oppression from heterosexuals by conforming to social expectations of opposite-gender sex and romance. This leaves some that identify as bisexual to be perceived as "not enough of either" or "not real". An Australian study conducted by Roffee and Waling in 2016 established that bisexual people faced microaggressions, bullying, and other anti-social behaviors from people within the lesbian and gay community.
Bisexual erasure (also referred to as
bisexual invisibility) is a phenomenon that tends to omit, falsify, or re-explain evidence of
bisexuality in
history, academia, the
news media, and other
primary sources, sometimes to the point of denying that bisexuality exists.
Kenji Yoshino (2000) writes that there are three concepts that cause invisibility within bisexuality: "The three invisibilities can be seen as nested within each other; the first affects straights, gays, and bisexuals; the second affects only gays and bisexuals; and the third affects only bisexuals." Forms of social standards and expectations, religion, and integrating the same-sex attraction aspect of bisexuality with homosexuality contribute to invisibility.
Claims of bisexuals adapting to heteronormativity Some forms of prejudice against bisexuals are claims that bisexuality is an attempt in persecuted homosexuals to adapt to heteronormative societies by adopting a bisexual identity. Such claims are criticized by bisexuals and researchers studying the situation of bisexuals for falsely assuming that same-sex relationships would somehow escape persecution in heteronormative cultures by simply identifying as bisexual instead of homosexual. These researchers cite that all countries with laws against sex between people of the same sex give the same punishment regardless of what sexual orientation the people found guilty identify as, that any countries where same-sex marriage is illegal never allow marriages between people of the same sex no matter if they identify as bisexual instead of homosexual, and that laws against "gay" male blood donors invariably prohibit any man who had sex with other men from donating blood no matter if he identifies as homosexual or as bisexual. The conclusion made by these researchers is that since there is no societal benefit in identifying as bisexual instead of identifying as homosexual, the claim that bisexuals are homosexuals trying to adapt to a heteronormative society is simply false and biphobic and causes bisexuals to suffer a two-way discrimination from both LGBTQ society and heteronormative society that is worse than the one-way discrimination from heteronormative society that is faced by homosexuals. It is also argued that such two-way discrimination causes many bisexuals to hide their bisexuality to an even greater extent than homosexuals hide their sexuality, leading to underestimations of the prevalence of bisexuality especially in men for whom such assumptions of "really being completely gay" are the most rampant. In the book
Bi: Notes for a Bisexual Revolution,
Shiri Eisner (2013) mentions Miguel Obradors-Campos' argument that bisexual individuals endure stigma by heterosexuals as well as gay and lesbian individuals. Eisner (2013) also writes, "some forms of biphobic stigma frequently observed in gay and lesbian communities: that bisexuals are privileged, that bisexuals will ultimately choose heterosexual relationships and lifestyles, that bisexual women are reinforcing patriarchy, that bisexuality is not a political identity, that bisexual women carry HIV to lesbian communities, and so on." The association of bisexuality with promiscuity stems from a variety of negative stereotypes targeting bisexuals as mentally or socially unstable people for whom sexual relations only with men, only with women, or only with one person at a time is not enough. These stereotypes may result from cultural assumptions that "men and women are so different that desire for one is an entirely different beast from desire for the other" ("a defining feature of
heterosexism"), and that "verbalizing a sexual desire inevitably leads to attempts to satisfy that desire." As a result, bisexuals may bear a
social stigma from accusations of cheating on or betraying their partners, leading a
double life, being "on the
down-low", and spreading
sexually transmitted diseases such as
HIV/
AIDS. This presumed behavior is further generalized as dishonesty, secrecy, and deception. Bisexuals can be characterized as being "slutty", "easy", indiscriminate, and
nymphomaniacs. Furthermore, they are strongly associated with
polyamory,
swinging, and
polygamy, the last being an established heterosexual tradition sanctioned by some religions and legal in several countries. This is despite the fact that bisexual people are as capable of monogamy or
serial monogamy as homosexuals or heterosexuals.
Tensions with pansexuals Bisexuals frequently struggle with myths and misconceptions about the definition of bisexuality, such as the idea that bisexuality conforms to the gender binary (thereby excluding attraction to nonbinary individuals), or excludes attraction to trans people in general. This sometimes creates tension between bisexuals and pansexuals, as pansexuals often see themselves as being more inclusive to a wider array of genders. A 2022 study by the
Journal of Bisexuality suggested that the majority of women who identify as pansexual or queer defined bisexuality as limited to attraction to cisgender men and women and critiqued bisexuality as reinforcing the traditional gender binary. However, bisexual women defined bisexuality as attraction to two or more, or "similar or dissimilar" genders, described bisexuality as inclusive of attractions to all genders, and reported negative psychological outcomes as a result of the debate around bisexual gender inclusivity. A 2017 study published in the
Journal of Bisexuality found that when bisexuals and pansexuals described gender and defined bisexuality, "there were no differences in how pansexual and bisexual people ... discussed sex or gender", and that the findings "do not support the stereotype that bisexual people endorse a binary view of gender while pansexual people do not." Definitions of bisexuality are historically transcendent of sex and gender, with authors such as Janet Bode, who published
View From Another Closet: Exploring Bisexuality in Women in 1976, noting, "Being bisexual does not mean they have sexual relations with both sexes but that they are capable of meaningful and intimate involvement with a person regardless of gender." This sentiment was echoed throughout the early bisexual community and touched on by bisexual activist
Lani Ka'ahumanu, who wrote in the 1987 article
The Bisexual Community: Are We Visible Yet?, "I am bisexual because I am drawn to particular people regardless of gender. It doesn’t make me wishy-washy, confused, untrustworthy, or more sexually liberated. It makes me a bisexual." Opposition to the pansexual label as distinct or separate from bisexuality, in particular due to ahistorical and biphobic implications, is also touched upon by Ka'ahumanu in the 25th anniversary edition of
