I was making out with a guy, french kissing. I had brushed my teeth about 45 minutes to an hour earlier. As we were making out I asked him his HIV status when he told me that he was positive. He said his viral load very very low. I am concerned about any small cuts that I may have gotten while brushing my teeth. I checked and I could not see any blood or cuts in my mouth. Is there any risk of contracting HIV this way? Do I need to be tested?
