Feeling confident...but: I had a one time encounter with a female escort. We had unprotected anal, I was insertive for maybe a minute or two. Of course, now I'm panicked. I've read hours of forums and advice and taken two tests. Knowing: She's mathematically unlikely to have HIV, she was adamant she was healthy/clean, I have no symptoms of anything after 3 weeks and I've had two 10-panel tests. Negative for everything at 4 days and 19 days (4th gen duo for HIV). How confident should I feel about having caught anything?
