Again, if this happens, your local genitourinary medicine clinic is the place to go.
It is possible to catch HIV by oral sex. The body fluids of a person who has HIV including semen and the natural fluids that lubricate the vagina will contain the virus.

Safe oral sex Do not perform oral sex on a man who has a discharge, or has recently had one that was not treated.
Do not perform oral sex on anyone whose genitals look unhealthy or unclean. If your partner has a cold sore on the face or lip, do not let him or her perform oral sex on you. Likewise, do not offer oral sex if you have a cold sore or think you might be getting one, or have any ulcers in your mouth.

The lower bowel contains many bacteria and viruses, which could enter the mouth, even if the anal area is washed beforehand.
