chances of HIV

I had unprotected play with another man around 7/25. He rubbed his penis around my anus and slid it in about half way a 2-3 times, but I asked him to stop and he did immediately. Anyway, broke out with herpes on my penis and possibly rectum about a week later. My bum and lips have had a unnoticeable rash but itchy (Chafe) for the last 5 weeks. I had a full panel of std tests on 9/2 (39 days), HSV2 pos, HIV neg (ELISA I think by Kaiser). My partner had a HIV test on 9/8 (at least 46 days or more?? after he might have contacted HIV from another) His was Negative also. Neither of us show any symptoms except I feel like I have thrush. I plan on getting rechecked in another week, I was told 4th gen from the std clinic is 98% after 3 weeks and Id be at 8 weeks. I think my risk is low, but I still have a hard time thinking of anything else, what do you think? I think my odds are low, but having trouble to sleep and stop stressing. what do you think?
