STI Risk Assessment Chart
Select an activity and the barrier method used to see the general risk level for STIs (like HIV, Chlamydia, Gonorrhea, Syphilis, HPV, Herpes). Note: This is a general guide. Risk varies based on viral load, open sores, and individual health.

Safer Sex Essentials
Understanding the basics of safer sex empowers you to make informed decisions about your sexual health and the health of your partners. Here is a breakdown of the key elements of safer sex.
Barrier Methods
Barrier methods physically block bodily fluids (and sometimes skin-to-skin contact) to reduce the risk of Sexually Transmitted Infections (STIs) and pregnancy.
- External Condoms: Worn over the penis or a sex toy. Usually made of latex, polyurethane, or polyisoprene.
- Internal Condoms: Inserted into the vagina or anus before sex. Offers slightly more protection for the outer genital area.
- Dental Dams: A thin, square piece of latex or silicone placed over the vulva or anus during oral sex.
- Gloves: Latex or nitrile gloves can be used during manual stimulation (fingering/fisting) to prevent the spread of STIs and keep fingernails from causing small tears.
Pro-Tip: Always use a compatible lubricant. Water-based or silicone-based lube is safe for most barriers, but never use oil-based lube (like coconut oil or Vaseline) with latex condoms, as it can cause them to break.
STI Testing Schedules
Regular testing is a normal, healthy part of an active sex life.
- General Rule: Test at least once a year, or before starting a relationship with a new partner.
- High-Risk or Multiple Partners: If you have multiple partners, casual encounters, or engage in higher-risk activities, consider testing every 3 to 6 months.
- After a Specific Incident: If a condom breaks, or you have an unprotected encounter with a partner of unknown status, consult a healthcare provider for testing timelines (some STIs take weeks to show up on tests).
PrEP (Pre-Exposure Prophylaxis)
PrEP is a daily pill (or long-acting injection) taken by people who do not have HIV to prevent getting HIV from sex or injection drug use. When taken as prescribed, PrEP is highly effective for preventing HIV. It does not protect against other STIs, so barrier methods are still recommended.
PEP (Post-Exposure Prophylaxis)
PEP is an emergency medication taken to prevent HIV after a possible exposure. It must be started within 72 hours (3 days) of the potential exposure to be effective, and it is taken daily for 28 days. If you think you've been exposed to HIV, seek medical attention immediately.
Vaccination Recommendations
Vaccines are a powerful tool for preventing certain viral STIs.
- HPV (Human Papillomavirus): The HPV vaccine (like Gardasil 9) protects against the strains of HPV most likely to cause genital warts and certain cancers (cervical, anal, throat). It's recommended for people of all genders, ideally before becoming sexually active, but can still be beneficial for adults.
- Hepatitis A and B: These viruses can be transmitted through sexual contact (especially anal play or exposure to bodily fluids). Vaccines are safe, effective, and widely available.
- Mpox (Monkeypox): Depending on current outbreaks and your risk factors, the Mpox vaccine may be recommended for certain individuals.
