2025 HIV Risk in Gay and Bisexual Men: Understanding Why It's Higher and How to Protect Yourself

As of 2019, nearly 1.2 million people in the United States were living with HIV, according to the Centers for Disease Control and Prevention (CDC), with approximately 13% unaware of their status.

Men who have sex with men (MSM) bear a disproportionate burden, accounting for around 65% of new HIV diagnoses in 2019, highlighting a critical public health challenge.

This article delves into why HIV prevalence is higher among MSM and outlines practical steps to reduce transmission risks.

Why Is HIV More Prevalent Among Men Who Have Sex With Men?

Globally, MSM are about 25 times more likely to contract HIV than the general population, according to UNAIDS data.

In the U.S., the majority of new HIV cases occur among gay, bisexual, and other MSM, increasing the likelihood of exposure within these communities.

Additional factors, including social, behavioral, and healthcare disparities, contribute to elevated transmission rates among MSM.

Modes of HIV Transmission

HIV spreads through direct contact with certain body fluids that contain the virus, including:

• Blood
• Semen and pre-seminal fluids
• Vaginal secretions
• Breast milk

While unprotected sexual contact is the most common transmission route, sharing needles or syringes, mother-to-child transmission during pregnancy or breastfeeding, and, rarely, infected blood transfusions or organ transplants can also transmit HIV.

Social and Structural Factors Influencing HIV Risk

HIV disproportionately affects Black and Hispanic MSM compared to their white counterparts, partly due to lower rates of preventive medication use and systemic barriers in healthcare access.

Stigma related to sexuality and HIV, along with experiences of discrimination and racism, further hinder prevention and treatment efforts in these communities.

Globally, restrictive laws against same-sex relationships limit access to HIV prevention and care for many MSM, especially in parts of Africa, Russia, and the Middle East.

The Impact of Stigma on HIV Prevention

Despite medical advances, stigma remains a significant barrier to HIV testing and treatment.

Fear of discrimination may lead MSM to conceal their sexual identity from healthcare providers, delaying diagnosis and access to preventive treatments.

Stigma also discourages HIV-positive individuals from adhering to treatment, which is vital to suppress viral load and reduce transmission risk.

Why Is Anal Sex a Higher Risk Activity?

Unprotected anal sex carries a higher risk of HIV transmission compared to vaginal sex because the lining of the anus is more delicate and prone to small tears, providing easier entry points for the virus.

Receptive partners in anal sex are especially vulnerable to acquiring HIV.

Challenges in HIV Testing and Treatment Uptake

Timely HIV testing and antiretroviral therapy are critical for preventing disease progression and reducing transmission.

The CDC recommends that MSM undergo HIV testing at least annually, with more frequent testing (every 3 to 6 months) advised for those at higher risk.

However, many MSM do not adhere to these guidelines, resulting in undiagnosed infections and delayed treatment.

In 2018, about one in six MSM with HIV in the U.S. were unaware of their status, and only 65% of HIV-positive gay and bisexual men received some form of HIV care.

Underutilization of PrEP and PEP Medications

Pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are effective medications that significantly reduce HIV acquisition risk.

PrEP involves daily medication for people at ongoing risk, while PEP is a short-term treatment started within 72 hours after potential exposure.

Despite their effectiveness, PrEP and PEP usage remains low among MSM, particularly among Black and Hispanic men, due to access barriers and healthcare provider hesitancy.

In 2017, CDC data showed PrEP use rates of 19% among Black MSM, 21% among Hispanic MSM, and 31% among white MSM.

Effective Strategies to Prevent HIV Transmission

1. Consistent Use of Barrier Methods

Using condoms and other barrier methods correctly every time during sex dramatically lowers the risk of HIV and other sexually transmitted infections.

2. Engage in Lower-Risk Sexual Activities

Activities like oral sex or those without fluid exchange carry less risk than unprotected anal sex.

3. Limit Number of Sexual Partners

Reducing the number of partners decreases potential exposure to HIV.

4. Regular HIV Testing and Timely Treatment

Routine testing enables early detection. If HIV-positive, adherence to antiretroviral therapy is essential to suppress viral load and prevent transmission.

5. Utilize PrEP and PEP When Appropriate

Consult healthcare providers about PrEP if at risk, and seek PEP immediately after a potential exposure to maximize protection.

Final Thoughts

HIV continues to impact MSM communities disproportionately each year. By adopting protective behaviors, accessing regular testing, and utilizing effective medical treatments, individuals can significantly reduce their risk of HIV infection.

Ongoing efforts to combat stigma and improve healthcare access are crucial to ending the HIV epidemic among gay, bisexual, and other MSM populations.
