Bisexual erasure is not a fringe concern. It is a daily experience for millions of people, and the mental health consequences are measurable, documented, and serious. If you identify as bisexual, you may already know the particular exhaustion of having your identity questioned from two directions at once — by straight people who assume you are experimenting, and by some in LGBTQ+ spaces who assume you will eventually "pick a side." That double dismissal has a name, and it has a cost.

What Bisexual Erasure Actually Means

Bisexual erasure — sometimes called bisexual invisibility — refers to the tendency to ignore, remove, falsify, or re-explain evidence of bisexual identity and experience. It happens in media when characters who are canonically bisexual get labeled gay or straight depending on their current relationship. It happens in conversation when someone says "oh, so you're straight now" after a bisexual person enters a different-sex relationship. It happens in health research when bisexual people are lumped into broader LGBTQ+ categories, obscuring what makes their experiences distinct. The effect is not just annoying. It is psychologically harmful in ways that compound over time.

The Research Is Clear

Studies consistently show that bisexual people report higher rates of anxiety, depression, and suicidal ideation than both heterosexual and gay or lesbian populations. Research out of the Williams Institute at UCLA Law found that bisexual adults experience poverty and food insecurity at higher rates than other sexual orientation groups, which correlates strongly with elevated mental health burden. A separate body of work from the American Institute of Bisexuality tracked how identity invalidation — being told your orientation is not real, not stable, or not worthy of acknowledgment — functions as a chronic stressor that activates the same stress-response pathways as other forms of discrimination. This is not about being oversensitive. When your identity is erased repeatedly, your nervous system registers that as a threat. And chronic, low-grade threat activation wears people down.

The Unique Isolation of Bisexual Experience

One underappreciated dimension of bisexual mental health is social isolation. Gay and lesbian communities have built robust social infrastructure — bars, organizations, pride events, affinity groups. Bisexual people often feel like guests in those spaces, welcome as long as they do not say the wrong thing or show up with the wrong partner. Straight social networks rarely offer the kind of understanding that comes from shared marginalized experience. The result is that bisexual people can end up stranded between communities, belonging fully to neither. Community belonging is one of the strongest predictors of mental wellness we know of. Removing it — or making it conditional — does measurable damage. Here is a thing most people do not think about: bisexual erasure affects mental health differently depending on relationship structure. Bisexual people in same-sex relationships often face pressure to perform more visible queerness to be taken seriously. Those in different-sex relationships face assumptions that they have "converted" to straightness. Either way, the relationship becomes a lens through which the identity is questioned rather than simply accepted. That pressure to constantly justify yourself is exhausting in a way that is hard to explain to people who have never experienced it.

What Actually Helps

Therapy that specifically affirms bisexual identity — not just generic LGBTQ+ affirmation — makes a meaningful difference. Bisexual-specific support groups and online communities have shown real benefit for the same reason: they provide a space where you do not have to spend energy defending the premise that your identity exists. Reducing biphobia within LGBTQ+ spaces matters too, and that is work the community needs to do rather than offloading it onto bisexual people to manage. If you are bisexual and struggling, please know that what you are experiencing has a structural cause. You are not fragile. You are responding to a world that keeps telling you that you do not exist — and that takes a toll on anyone.
