Jabarkan Bentuk dari Bifobia

Bifobia dapat mengakibatkan orang-orang menganggap bahwa biseksualitas "tidaklah nyata", dengan menekankan bahwa orang yang mengaku biseksual tidaklah murni biseksual, atau bahwa fenomena biseksualitas lebih jarang terjadi daripada klaim yang ada. Salah satubentuk penyangkalan ini didasari pada pandangan heteroseksis bahwa heteroseksualitas adalah satu-satunya orientasi seksual yang alami. Penyimpangan dianggap sebagai sebuah patologi psikologis atau sebuah perilaku antisosial. Dengan demikian, homofobia dan bifobia tidaklah banyak berbeda secara substansi.

Bentuk penyangkalan lainnya adalah berdasarkan pandangan biner akan seksualitas : bahwa semua orang dianggap monoseksual, atau dengan kata lain hanya gay/lesbian atau heteroseksual. Pada tahun 1980s, kajian modern terhadap seksualitas didominasi gagasan bahwa orientasi seksual yang sah hanyalah heteroseksualitas dan homoseksualitas, manakala biseksualitas dianggap sebagai "homoseksualitas kedua". Kaum biseksual dianggap sebagai orang-orang homoseksual yang tidak terang-terangan akan identitas mereka atau seseorang (baik gay/lesbian maupun heteroseksual) yang ingin bereksperimen secara seksual di luar seksualitas "biasanya". Pernyataan seperti "hanya ada orang gay, heteroseksual atau pembohong" merupakan pengejawantahan pandangan dikotomi akan orientasi seksual.

Ada pula yang menerima keberadaan teoretis biseksualitas tetapi dengan pemahaman terbatas sebagai ketertarikan yang sama terhadap laki-laki dan perempuan. Kaum biseksual yang tidak memiliki ketertarikan yang sama pada kedua gender dianggap sebagai homoseksual atau heteroseksual, tergantung pada tingkat preferensi mana yang lebih tinggi. Ada pula yang hanya mengakui bahwa perempuanlah yang dapat menjadi biseksual, dan menyangkal keberadaan lelaki biseksual.

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.

Tuduhan bahwa lelaki biseksual bersikap homofobik

One cause of biphobia in the gay male community is that there is an identity political tradition to assume that acceptance of male homosexuality is linked to the belief that men's sexuality is specialized. This causes many members of the gay male community to assume that the very idea that men can be bisexual is homophobic to gay men. A number of bisexual men feel that such attitudes force them to keep their bisexuality in the closet and that it is even more oppressive than traditional heteronormativity. These men argue that the gay male community have something to learn about respect for the individual from the lesbian community, in which there is not a strong tradition to assume links between notions about the origins of sexual preferences and the acceptance thereof. These views are also supported by some gay men who do not like anal sex (sides, as opposed to both tops and bottoms) and report that they feel bullied by other gay men's assumption that their dislike for anal sex is "homophobic" and want more respect for the individuality in which a gay man who do not hate himself may simply not like anal sex and instead prefer other sex acts such as mutual fellatio and mutual male masturbation.
