One night stand. girl fingered herself, then licked her fingers. five minutes later she repeatedly spit on my penis to lubricate a vigorous handjob. some kisses. no other contact. emergency room 18 hours later they put me on pep. what is hiv risk?

HIV and saliva: Saliva is usually not a mode of transmission unless open sores/bleeding in the mouth - which you can not be sure. The risk is likely low but not 0 ( in medicine nothing is zero), so continue PEP for added safety https://www.cdc.gov/hiv/basics/transmission.html https://www.hiv.gov/hiv-basics/overview/about-hiv-and-aids/how-is-hiv-transmitted https://www.ncbi.nlm.nih.gov/pubmed/9989543
