HIV risk and test results

Hi!
Could you please help me with the following doubts about HIV infection? I´m really worried at the moment!
I´m a 27 years-old male living in Brazil and had a single sexual partner (girl) for the past 6 years. However, last month I had sexual contact with another guy, a single time. We didn´t do neither penetration nor oral sex, but I happened to be in contact with his semen after mutual masturbation. The contact was in the chest and some tiny droplets eventually splashed in the face. Not sure if it contacted the mouth or eyes. I immediately had a shower to clean the chest and washed the mouth using tooth paste. The guy has a more promiscuous sexual behavior, but I´m not aware of his HIV status.
So, I´m really anxious about the real chances of this sexual contact leading to an HIV infection, mainly because now (6 weeks) I´m having joint pain.
I had the following HIV tests:

- 15 days: RNA – PCR test – RESULT: undetectable
- 21 days: Fourth generation (Ag/Ab) test – RESULT: Negative
- 35 days: Fourth generation (Ag/Ab) test – RESULT: Negative
- 35 days: RNA – PCR test: awaiting results

Do you think these tests are conclusive?
Please help me!
Thanks in advance.

You had no risk, so you had no reason to test. Since you did test and over test they prove you don't have HIV. NO TESTING NEEDED.
