Can I get HIV from Kissing?
There are four fluids that can carry and transmit HIV: blood, semen, vaginal fluids, and breast milk. Saliva doesn't transmit it.
It is, however, THEORETICALLY possible to contract HIV through kissing. If both partners have cuts or sores in the mouth or bleeding gums (like after brushing or flossing your teeth), infected blood could possibly be exchanged. However, in practice this is EXTREMELY unlikely. There is something about saliva and the environment of the mouth that is inhospitable to the virus. Like all safe sex, kissing is a matter of managing risks. If you are aware of cuts or sores in your mouth, it is best to abstain from "deep kissing," but in general kissing is one of the safest sexual activities.
