Bisexual Men, HIV/AIDS & the “Bridge” Myth

During the HIV/AIDS crisis, bisexual men were often portrayed as a danger to women and heterosexual society. But that was only one part of the story. Bisexual activists were also developing safer-sex education, improving public-health records, and reaching people whose needs were being overlooked.

Understanding this history means holding two realities together: HIV transmission through different sexual networks was a genuine public-health concern, and turning an entire sexual orientation into a symbol of danger was neither fair nor scientifically justified.

How the “bisexual bridge” became a public fear

As the AIDS crisis unfolded in the 1980s, public discussion often divided people into supposedly separate groups: gay men on one side and the heterosexual population on the other. Bisexual men were sometimes described as a “bridge” through which HIV could pass between them.

This language made an epidemiological question sound like a judgment about identity. It also encouraged a misleading idea: that a man’s bisexuality, rather than particular exposures and prevention measures, was enough to indicate whether he posed a risk.

The framing is visible in historical reporting. In February 1987, TIME published Martha Smilgis’s “The Big Chill: Fear of AIDS”. Alongside a broader discussion of fear, dating and HIV prevention, the article depicted sexually active bisexual men as one possible route of transmission to female partners. Two months later, The New York Times published Jon Nordheimer’s “AIDS Specter for Women: The Bisexual Man.”

These reports should be read in their historical context. The virus was still poorly understood by much of the public, treatment options were extremely limited, and people were frightened. Yet even in 1987, the reporting contained competing voices. The New York Times article acknowledged that some experts considered the perceived threat exaggerated. Bisexual activist David Lourea warned that singling out bisexual men could encourage scapegoating while giving a false sense of safety around other partners.

The danger was real; the stereotype was not a reliable way to understand it.

What did research actually find?

It would be inaccurate to claim that sexual transmission from men with male and female partners never happened. It did. A responsible account must distinguish the existence of a transmission route from assumptions about how common it was—and from judgments about people who identified as bisexual.

In 1997, researchers led by James G. Kahn published “How many HIV infections cross the bisexual bridge?” Their model estimated around 400 annual HIV transmissions to women from male partners who also had sex with men, across the high-risk US cities included in the research. The estimate varied substantially with the assumptions used. The researchers described this route as a relatively minor component of the roughly 40,000 total annual US HIV infections estimated at the time. These figures refer to different geographical populations and are not directly comparable counts.

That result does not mean every city or every period looked alike. It was a model using particular data and assumptions, not a universal measurement of everyone’s experience. It does, however, challenge the idea that bisexual men could reasonably be treated as the principal explanation for HIV spreading among heterosexual women.

There is another problem with the label itself: sexual orientation and sexual behavior are related but different. Not every man who has sex with men identifies as gay or bisexual. Not every bisexual man has sex with more than one gender, or is sexually active at all. Public-health approaches work best when they consider actual behavior, access to prevention, treatment and care—not guesses based on a label.

The people doing the prevention work

While parts of the public conversation focused on bisexual men as potential transmitters, bisexual advocates were already working to prevent infections and make sexual-health services more useful.

David Lourea: education and recognition in health statistics

Historian and bisexual activist Loraine Hutchins documents that David Lourea and Cynthia Slater were providing safer-sex education in San Francisco bathhouses and BDSM clubs as early as 1981. This was community-based work in places where people could discuss actual sexual practices and prevention without relying on stereotypes about identity.

By 1983, Lourea was serving on San Francisco’s AIDS Education Advisory Committee. In 1984, after sustained advocacy, he persuaded the city’s public-health department to identify bisexual men in its weekly AIDS reporting rather than leave them indistinguishable in broader categories. This mattered because people who are invisible in health data can also become invisible in planning, education and support.

Lourea’s contribution was not limited to public advocacy. In 1992, he co-authored the peer-reviewed paper “HIV prevention: A dramaturgical analysis and practical guide to creating safer sex interventions” with Clark L. Taylor, exploring ways to make prevention more responsive to social situations and changing behavior. His papers are preserved by the San Francisco Public Library, including materials on bisexual community life and AIDS education.

Cynthia Slater: practical information for overlooked communities

Cynthia Slater helped bring sexual-health education into spaces that mainstream messaging could easily overlook. Her work included explaining safer practices within BDSM communities. In 1985, she established the Women’s HIV/AIDS Information Switchboard in San Francisco, according to Hutchins’s historical account.

Slater’s work illustrates why effective prevention cannot simply tell people to be afraid. It needs to provide information that is relevant, understandable and respectful of the people receiving it.

Lani Kaʻahumanu and prevention for lesbian and bisexual women

Bisexual women were also at risk of being overlooked in HIV discussions, particularly when services assumed that women who had sex with women did not need relevant sexual-health information.

According to Hutchins’s historical account, from 1992 to 1994, Lani Kaʻahumanu coordinated a prevention and education research project at Lyon-Martin Women’s Health Services, supported by an American Foundation for AIDS Research grant. The work focused on young lesbian and bisexual women.

A separate study from the same period illustrates another community-based approach. A 1994 study by Patricia E. Stevens reported interviews with 626 women in San Francisco bars and clubs and group presentations reaching 1,315 attendees. The study found interest in HIV-prevention information and intentions to change behavior. It did not establish how many infections were prevented.

Bisexual organizations made AIDS education a priority

This was not only the work of individual activists. The East Coast Bisexual Network, founded in 1985 and later known as the Bisexual Resource Center, made HIV/AIDS education and activism a priority in the late 1980s. Northeastern University’s archive specifically records how the network responded to accusations that bisexual people were carrying the disease between communities.

Education, advocacy, community records and the preservation of bisexual voices were all part of the response.

What stigma obscured—and why it still matters

The “bridge” narrative did more than describe a possible pathway for infection. It often portrayed heterosexual women as innocent and bisexual men as suspect, while doing little to explain how anyone could access better information, safer-sex supplies, testing or appropriate care.

It could also obscure the experiences of bisexual people living with HIV themselves. In a 2021 Australian study, bisexual men living with HIV reported higher levels of internalized HIV stigma and less social connection than gay men in the surveyed sample. Only 48 participants identified as bisexual men, so those findings should not be generalized to everyone. They nevertheless point to support needs that can disappear when gay and bisexual men are routinely treated as one undifferentiated group.

Historic stigma cannot, on its own, explain every contemporary difference in healthcare. But the history shows why inclusive language and better recognition matter: people need to be seen as people seeking care, not as stereotypes or transmission routes.

What HIV prevention tells us today

Modern HIV prevention is far more effective than the options available in the early years of the crisis. HIV risk is related to specific exposures, not to whether someone is bisexual, gay or straight.

The US Centers for Disease Control and Prevention (CDC) describes tools including HIV testing, condoms, pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP). Treatment is prevention, too. Under U=U—Undetectable = Untransmittable, a person living with HIV who takes treatment and maintains an undetectable viral load does not transmit HIV to sexual partners.

None of this removes the importance of honest conversations about sexual health or respect for relationship agreements. It means those conversations should be based on relevant facts and mutual responsibility, not on suspicion attached to a sexual orientation.

Remembering a fuller history

The HIV/AIDS crisis caused immense loss, and the response depended on the work of people across many communities: people living with HIV, gay and lesbian organizers, bisexual and transgender activists, healthcare workers, researchers and allies.

The bisexual part of that history deserves to be told accurately. At a time when bisexual men were sometimes portrayed as a dangerous “bridge” for the virus, bisexual activists were helping build something very different: connections to education, prevention, recognition and care.

The lesson is not that bisexual people were outside the epidemic. They were part of it—as people affected, as people needing support, and as people helping others survive.
