I recently kissed a girl lightly (no french kissing) , problem is I had a small mouth ulcer on my inner lower lip and also chapped lips and wasn't sure if she too had sores too and maybe blood. I noticed when i pressed the ulcer hard enough i could see some blood. My question is there a chance of HIV infection from her via the ulcer assuming she had some blood or maybe sores?(though i didn't notice any blood or sores) Answers greatly appreciated
