Girl was deep kissing guy A quite vigorously. End of the party, she kissed (pecked, closed mouth) guy B goodbye on the lips, then did the same to me also, before leaving. I did not have any cuts in the mouth or on my lip, but was a little tender right at the junction of my lip due to dry lips. Assuming there were traces of HIV + Hepatitis C virus blood in her saliva, is there any exposure risk to me? Thanks.
