If you have read any questions on this forum, you have seen what the risks are. The ONLY risks for HIV are unprotected vaginal or anal intercourse or sharing IV drug needles. No, kissing is not a risk in any way. Saliva and air inactivate the virus. This includes if people have cuts in their mouth). Pep is not recommended. Pep is not usually given for unprotected sex either as HIV is very hard to actually transmit. The time when PEP is given is when you have unprotected sex from a person KNOWN to have HIV. There is less than a one percent chance of transmission from a single unprotected se exposure. From kissing? zero percent risk.
