Oral (in the mouth) sex is when someone licks, sucks, or kisses a partner’s genitals or anus. It is possible to get and pass on STIs through oral sex, although it’s usually lower risk than for vaginal or anal sex without a condom.
If you’ve given someone oral sex, you can order a throat swab to test for chlamydia and gonorrhoea in your throat. These are available as part of our Standard and Comprehensive STI test kits.
If you’re not sure whether you’ve been at risk, you might find it helpful to talk to a health adviser or nurse at a sexual health clinic.
