Oral sex

You can get a sexually transmitted infection (STI) by giving or getting oral sex.

Gonorrhea, Chlamydia, Herpes, Hepatitis B, Syphilis and HIV can all be spread through oral sex.

What increases my risks during oral sex?

• Having small cuts in your mouth. Cuts may be from dental work, brushing or flossing before/after oral sex, gum disease, or sharp foods. Cuts may be so small that you do not notice.
• Sores on the mouth or genitals caused by rough or prolonged oral sex or an STI such as Herpes or Syphilis.
• If the person receiving oral sex is menstruating (having her period).
• Holding semen or vaginal fluid in your mouth for a long time or swallowing it.

How can I reduce the risk of HIV and STIs during oral sex?

• Use a latex or polyurethane condom for oral sex on the penis.
• Use a modified condom* or dental dam for oral sex on the vagina.
• Try to avoid getting or keeping semen or vaginal fluids in your mouth.
• Avoid brushing or flossing your teeth within 30 minutes of giving oral sex.
• Use anti-bacterial mouthwash after oral sex.

*A condom can be used to make a dental dam. Carefully take the condom out of its package and unroll it. Cut off the tip and end of the condom and cut down the length of the tube. Unroll the condom and you will have a rectangular sheet that can be used as a dental dam.
