Oops... Sorry I misread.. You already had tests done....
The RNA pcr is a good indicator that you're negative ( although some would say its conclusive) the 4th gen ag/ab done at 2 weeks is a bit too early. Anyways.. Since you've passed the 3 month mark , you might want to follow up with a standard ab test to conclude.
If you did penetrate without condom, please test.
You had no risk of HIV and didn't have to test in the first place. Rubbing carries no risk.
