How high is it for me to get hiv, french kissed with my roof of mymouth scraped from food i ate. kissed once barely tongue. how many get infeced?

Rare to get infected: It would be very, very unlikely to get infected unless the roof of your mouth was bleeding and he had wounds on the tongue. But the big question is and advice is why become sexually involved with an HIV person, and you need to ask anyone who gets physical about sexually transmitted diseases of all types and take precaution.
