You can get HIV from oral sex, but the chance of infection is very low. HIV is the AIDS virus, and HIV is found in the body fluids of an infected person, such as blood, semen, breast milk, and vaginal secretions. There are three general modes of transmission: blood transmission, sexual contact, and mother-to-child transmission. The amount of HIV in the saliva of an HIV-infected person is very small, and there are enzymes in the mouth, such as lysozyme, that kill HIV. if the other person’s genitals are broken and there has been some time of contact, there is a possibility of infection, but the chances of infection are very small. If the other partner has mouth ulcers, bleeding gums, etc., there is also a possibility of getting infected with HIV after coming into contact with the HIV-infected person’s blood, vaginal secretions, or semen. It is recommended not to have multiple sexual partners and to take safety precautions, such as wearing a condom, when having sex.
