I agree that this isn't a risk. Only risks are unprotected vaginal or anal sex or sharing IV drugs. You'd know if the condom broke, it's very noticeable. Hand jobs are no risk even without a condom. So, you should not worry, no risk for HIV, no need to test.
Micro tears are a myth. If a condom fails it is a large rip down the seam and it hangs in tatters and is hard to take off. None of that happened so move on back to your happy life and stop worrying about something that didn't happen.
