Language is weird. You’ve probably noticed that in medical offices or on public health posters, the phrase men who have sex with men—often shortened to MSM—pops up everywhere. It feels clunky. It feels detached. It almost feels like something a robot would say to describe a human being’s love life.
But there’s a reason it hasn’t gone away.
Historically, this term wasn't created to be inclusive or "woke." It was actually a pragmatic tool used by epidemiologists back in the 1990s. They realized that if you only asked people if they were "gay" or "bisexual," you missed a massive chunk of the population who were at risk for certain health issues but didn't identify with those labels. Some men are married to women. Some are just "straight-acting" guys who hook up on the side. Some find "gay" to be a political statement they aren't interested in making.
So, public health officials shifted. They stopped asking who you are and started asking what you do.
The Identity Gap in MSM Health
It’s honestly a bit of a disconnect. You have someone like Dr. G.W. Rutherford, who was instrumental in early HIV research, explaining that behavior doesn't always equal identity. You can have a guy in rural America who has sex with other men but would never, ever walk in a Pride parade. If a doctor only asks, "Are you gay?" that guy says "No," and suddenly he isn't getting the right screenings or advice on PrEP (Pre-Exposure Prophylaxis).
This isn't a small group.

In many global studies, specifically across parts of Africa and Southeast Asia, the term men who have sex with men allows health workers to provide care without forcing a social or political label on someone that might actually put them in danger. In countries where being gay is criminalized, "MSM" is a clinical shield. It focuses on the biology and the transmission of viruses rather than the "lifestyle."
But here’s the kicker: the term is starting to age poorly in Western clinical settings.
A lot of younger guys find it dehumanizing. They feel like it strips away their culture and boils them down to a physical act. When you look at the research coming out of places like the Fenway Institute in Boston, there’s a growing push to move toward "Sexual and Gender Minorities" (SGM) as a broader, more humanizing umbrella. Yet, for now, if you’re looking at CDC data or WHO reports, MSM remains the gold standard for data collection. It’s about the numbers. It’s about tracking how things like Mpox or HIV move through a community so resources can be dumped where they are needed most.
Why Biology Doesn't Care About Your Label
Viruses are simple. They don't check your Tinder profile to see if you're "questioning" or "queer."
For men who have sex with men, the health landscape has changed more in the last ten years than in the previous fifty. We have PrEP now. It’s a game-changer. Basically, it’s a daily pill (or a bimonthly injection like Apretude) that reduces the risk of getting HIV from sex by about 99%. That is staggering. It basically turned a death sentence into a manageable, and often preventable, condition.

But access is messy.
If you aren't "out" to your primary care doctor, you might not hear about it. This is where the MSM label actually helps. If a doctor sees "MSM" on a chart, they (hopefully) know to check for things that aren't on the standard panel. Think about rectal gonorrhea or pharyngeal chlamydia. Most "straight" panels don't swab for those. If you're a man having sex with men, and your doctor only takes a urine sample, they are missing half the picture. Literally. You could walk out with a clean bill of health while carrying an infection that is slowly becoming antibiotic-resistant.
The science is clear: site-specific testing is non-negotiable.
Then there’s the mental health side of things. It’s not just about what happens in the bedroom. Society puts a specific kind of pressure on men who don't fit the heteronormative mold. Minority stress—a term coined by Ilan Meyer—explains how the chronic stress of being part of a marginalized group leads to higher rates of anxiety and substance use. It isn't that being MSM makes you more prone to these things naturally; it’s that the world makes it harder to just be.
Navigating the Healthcare System
So, how do you handle this if you fall into this category?

First, honesty with a provider is the only way to get actual care. If your doctor makes you feel weird, fire them. Seriously. There are directories like OutCare Health or the GLMA (Gay & Lesbian Medical Association) that list providers who actually understand the nuances of MSM health.
You need to be asking for:
- Full-panel STI screenings (including throat and rectal swabs).
- PrEP consultations if you have multiple partners.
- Hepatitis A and B vaccinations (MSM are at a statistically higher risk for certain outbreaks).
- HPV vaccines (Gardasil 9 isn't just for teenagers; it helps prevent anal cancers later in life).
It’s about being your own advocate. The system is built on averages, and if you aren't the "average" patient, you’ll fall through the cracks.
The Future of the Label
Will we still be using the phrase "men who have sex with men" in 2030? Maybe not. As society becomes more comfortable with fluid identities, the need for a clunky clinical bridge might vanish. We might just talk about "patients with prostate health needs who engage in receptive anal intercourse." It’s more specific and less about an "identity" that someone might not even want.
But for now, the term serves a purpose. It’s a bucket. It holds the data that saves lives.
If you are a man who has sex with men, or if you're a provider working with this population, the goal shouldn't be to get hung up on the terminology. The goal is the health outcome. It’s about making sure the guy who identifies as straight but has a male partner on the side gets the same life-saving PrEP as the loudest guy at the disco.
Actionable Steps for Better Health Advocacy:
- Find a Culturally Competent Provider: Use the GLMA Provider Directory to find a doctor who won't blink when you discuss your sexual history. This avoids the "explanation fatigue" that comes with teaching your doctor about your own life.
- Demand Three-Site Testing: If you are sexually active, ensure your STI screenings include the pharynx (throat), rectum, and urethra. A standard urine test misses up to 70% of infections in MSM.
- Assess Your PrEP Eligibility: Even if you use condoms, PrEP provides a secondary layer of protection that is nearly foolproof when taken correctly. Talk to your doctor or visit a local sexual health clinic to see if a daily pill or a long-acting injectable is right for your lifestyle.
- Mental Health Check-Ins: Recognize that "minority stress" is real. If you find yourself using substances to cope with social anxiety or identity issues, seek out therapists who specialize in LGBTQ+ or MSM issues specifically.
- Vaccination Status: Double-check that you have completed the series for Hepatitis A, Hepatitis B, and HPV. These are often overlooked in adult men but are crucial for long-term health in the MSM community.
