This guide is educational information about sexual health for adults — it is not medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified doctor or sexual-health clinic. It does not diagnose, treat, cure, or prevent any condition. See a doctor or clinic for testing, diagnosis, contraception advice, and treatment, and do not start or stop any medication without medical advice. Regular STI testing is an important part of sexual health. Seek prompt medical care for severe pelvic or genital pain, signs of infection (fever, unusual discharge, or sores), or any reaction to medication; in a medical emergency, call 911.
