What infections can I catch through oral sex?
Oral sex is the stimulation of the genitals using the mouth and tongue. It is one of the ways that sexually transmitted infections (STIs) are most frequently passed on.
You can catch an STI if you have just one sexual partner, but the chance of catching an infection increases the more partners you have.
STIs that are commonly caught through oral sex are:
Infections that are less frequently passed on through oral sex include:
hepatitis A, hepatitis B and hepatitis C
Symptoms of STIs
The symptoms of an STI vary depending on the type of infection. However, most STIs are treatable if detected early enough. If you suspect that you may have an infection, it is important to visit your local family planning clinic, or genito-urinary medicine (GUM) clinic, as soon as possible.
Find your nearest sexual health service.
If left untreated, STIs are not only uncomfortable and embarrassing, but they can seriously affect your health and fertility.
You can prevent catching STIs during oral sex by making sure that you or your partner wear a condom.
You can use a dental dam to cover the anus or female genitals during oral sex. A dental dam is a latex or polyurethane (very thin, soft plastic) square, of about 15cm by 15cm. It acts as a barrier to help prevent STIs passing from one person to another.
