Hi.
The chances of getting or giving HIV from rimming are low. Blood on or around the anus or mouth could increase the chance of passing HIV.
There are other STIs that are more easily be passed through rimming including hepatitis A, herpes, syphilis and HPV. It is possible but not common to pass gonorrhea and chlamydia.
It is also possible to pass or get intestinal parasites.
Barriers, such as dental dams can provide good protection against STI’s.
