I am an apparently healthy man and had 3 sexual encounters with a man whom I later found out to be HIV positive. The first time was only kissing and foreplay, which included rimming i.e him on me. He put on a condom to penetrate me but I stopped him, it was my first time painful and he didn't enter far. I did give him oral and got a small amount of precum in my mouth. The second time was the following day, he penetrated with condom and came. I saw him take off the condom with his semen in it. I was careful giving him oral the second time and wiped off any precum with my palm before putting it in my mouth. The third time was ten days later, he also used condom but didn't come, and we had foreplay which included oral but little or no precum in my mouth. We did kiss a lot during all 3 encounters. It was during the third time I noticed he had enlarged lymph nodes and quickly withdrew from him. I made him take the test in the morning and once I found out he was positive, I got myself on Post exposure Prophylaxis the same day. I am worried that if he put the condom on wrong or had a high viral load in the precum that entered my mouth I may be infected. I also have a lot of fatigue, headaches and occasional mild fever since I started taking the drugs. What are the chances I am infected?
