text: On the Cheek: \n\nHIV is not transmitted casually, so kissing on the cheek is very safe. Even if the other person has the virus, your unbroken skin is a good barrier. No one has become infected from such ordinary social contact as dry kisses, hugs, and handshakes. \n\nOpen-Mouth Kissing: \n\nOpen-mouth kissing is considered a very low-risk activity for the transmission of HIV. However, prolonged open-mouth kissing could damage the mouth or lips and allow HIV to pass from an infected person to a partner and then enter the body through cuts or sores in the mouth. Because of this possible risk, the CDC (Center for Disease Control) recommends against open-mouth kissing with an infected partner. \n\nOne case suggests that a woman became infected with HIV from her sex partner through exposure to contaminated blood during open-mouth kissing.\n\nAs far as oral sex, yes if there is an open wound in either place.
