LGBTQ+ Sexual Health

Why this topic needs its own guidance

Sexual health is part of overall health for everyone, but the practical detail differs depending on anatomy, the kinds of sex a person has, and the medications or procedures involved in their care. Generic advice written around one assumed set of circumstances leaves real gaps — which screening sites are relevant, which vaccines apply, how hormone therapy interacts with other health needs.

There is also a well-documented access problem. Many LGBTQ+ people delay care because they anticipate bias, or because they have encountered clinicians without relevant knowledge. The NHS notes that lesbian, gay, bisexual, and transgender people are at higher risk of some mental health difficulties, linked to discrimination and stigma rather than to identity itself. Delayed care compounds both problems.

This section brings together evidence-based guidance from the CDC, WHO, NHS, and HIV.gov so you can understand your options and arrive at an appointment knowing what to ask for.

HIV prevention has changed substantially

Two developments have reshaped prevention. First, pre-exposure prophylaxis: HIV.gov reports that PrEP reduces the risk of acquiring HIV from sex by about 99 percent when taken as prescribed. Second, treatment as prevention: the CDC states that people living with HIV who take treatment as prescribed and maintain an undetectable viral load have effectively no risk of transmitting HIV to sexual partners — the principle known as Undetectable = Untransmittable.

For emergencies, post-exposure prophylaxis is a course of medication started after a possible exposure. HIV.gov is explicit that it must begin within 72 hours, and the sooner the better.

Start with what is PrEP, what is PEP, and understanding undetectable = untransmittable. All three involve decisions to make with a provider who knows your history.

Screening that matches your actual risk

Testing is most useful when it covers the right sites. The CDC screening recommendations are organised around exposure and anatomy — which is why throat and rectal swabs are included for some people, and why a urine test alone can miss infections. Our guides cover STI prevention for men who have sex with men, sexual health for women who have sex with women, and inclusive STI testing for LGBTQ+ people, along with broader safer sex and prevention guidance.

Affirming and competent care

For transgender and gender-diverse readers, transgender sexual health basics and gender-affirming care explained cover the health needs that persist regardless of transition status, including which screenings remain relevant based on the organs a person has. To find supportive clinicians, read finding LGBTQ+-affirming healthcare. Because well-being is whole-person, we also address LGBTQ+ mental health and well-being.

What people get wrong

"Women who have sex with women do not need STI screening." Several infections, including HPV and herpes, transmit through skin contact and shared items. Screening still applies.

"PrEP covers everything." It prevents HIV only. Condoms, vaccination, and regular testing remain relevant.

"HPV vaccination is only for women." It protects against cancers and genital warts that affect people of all genders.

"Gender-affirming care means surgery." It is a broad category that may include social, hormonal, or surgical elements, or none of them, depending on the person.

When to see a healthcare provider

• Immediately, and within 72 hours, after a possible HIV exposure — PEP is time-limited.
• If you are considering PrEP, which requires baseline testing and ongoing monitoring.
• If you have symptoms: sores, unusual discharge, pain when passing urine, rectal pain or bleeding, or an unexplained rash.
• For routine screening at the interval recommended for your circumstances, even without symptoms.
• If you are starting, stopping, or changing hormone therapy, or if low mood, anxiety, or thoughts of self-harm are affecting you.
