Thanks. I'm less worried.
As an adult, the only risks for HIV are:
1) having unprotected, penetrative vaginal or anal sex, or
2) sharing IV drug needles with other IV drug users.
You had no risk and do not need to test, and YES, I am taking into account the fact that he is HIV+. No one has ever contracted HIV from a hand job, whether the person they received it from had cuts, scrapes or rashes on their hands. There is nothing you could add to this scenario that would make it a risk.
You had zero risk and you do not need to test.
