I'm going to explain in great detail what I experienced in order to form a clear picture.
A girl and I were making out, she mentioned that she was "wet" and touched her vagina, sticking one finger inside. She then put that finger into her mouth . A few minutes later she washed her hands. Then a few minutes after that she performed a handjob on me, with lube. I ejaculated. As far as I could tell there were no open cuts on her hand. She also did not use her saliva in any way. I had recently shaved my genitals, including the base of my penis, and I noticed there were a few small cuts, very small openings, more like slightly ingrown hairs actually.
My question is, am I at risk? What are the chances that she could have transmitted HIV to me, assuming she had it?
