HIV infects humans and causes damage by taking over cells in the immune system—the part of the body that usually works to fight off germs, bacteria and disease. When that happens, the body may not be able to fight off certain types of illnesses or cancers. If the infection is not detected and treated, the immune system gradually weakens and AIDS develops. HIV and AIDS are terms that are often used together, and sometimes are used interchangeably, though they are not the same thing. If you are worried about a recent potential exposure, go to the emergency room and ask for PEP post-exposure prophylaxis as soon as you can.
So that perhaps explains the reason why we get asked this sensible question so often: does oral sex put me at risk of getting HIV? Oral sex is generally considered to be very low risk for HIV transmission. Risk can increase if there are sores, abrasions or cuts in the mouth or following a dental procedure like tooth extraction. The best advice is to avoid getting cum in the mouth in these circumstances. HIV needs an entry point such as a cut to be transmitted, so you may want to avoid getting these fluids in your mouth if you have bad gingivitis, an STI in the throat or other sores in the mouth. HIV transmission from oral sex is very rare whatever you choose. These are all bacterial infections, so the good news is they are easily treated and cured.
Oral sex is generally a low risk activity. It is likely to be zero or close to zero in most circumstances. This will be higher depending on these factors:. In practice, condoms are very rarely used for oral sex. This partly because condoms make oral sex so much less pleasurable for both partners and are more intrusive for oral compared to vaginal or anal sex.
