You were safe !!!!!
It's much better to be in a long term monogamous relationship
You never had a risk for HIV. The only risks for HIV include having unprotected vaginal or anal sex or sharing IV drug needles. Nothing transmits during a hand job. Air inactivates the virus. So, you never needed to test in the first place. No risk means that every and any test you take will be negative. Can't get something you had nor risk of doing so, right? So, no, do not repeat the test. You don't have HIV.
