Can you get an STI from oral sex?
Last updated September 3, 2026.
Yes - the CDC lists chlamydia, gonorrhea, syphilis, herpes, HPV, and HIV as spreadable through oral sex, and many of these infections cause no symptoms, which is why they keep moving. Throat gonorrhea and chlamydia are typically silent and still transmissible; HIV via oral is the low end of the risk scale but not zero. Protection: condoms or dental dams for every act, skipping oral sex when sores or symptoms are present, and not brushing or flossing right before. The missed piece: standard panels do not swab the throat - ask for throat and rectal testing if oral sex is part of your life.
What to do
- Use barriers every time. Condoms and dental dams are the CDC's first line.
- Pause for sores or symptoms. On either partner, on mouth or genitals.
- Ask for throat swabs specifically. Standard STI panels miss the throat.
- Test on a schedule that matches your life. New or multiple partners: every 3 to 6 months is the usual cadence.
