A sexually transmitted infection is passed mainly by sexual contact. Chlamydia, gonorrhea, syphilis, herpes, HPV, HIV, and trichomonas sit on the usual list. Some announce themselves with discharge, sores, or pain. Some stay quiet while they do damage or while they wait to be passed along.

Testing is how you find the quiet ones. Treatment ranges from a short antibiotic course to long-term antiviral care. A partner conversation after a diagnosis is uncomfortable and still required if other people may be affected.

Condoms cut risk. They do not create purity. Stigma delays care, which is how infections move. A clinic nurse has heard your story before. Say the plain words.
