No, this is not a risk for HIV. Since you aren't new here, I'm surprised you ask this question. I'm sure you've read what the only risks for HIV transmission are but I'll repeat them for you. Adults only get HIV from unprotected vaginal or anal sex or sharing IV drug needles. This is zero risk and you do not need to test. Air inactivates the virus. Fingering is never a risk. Even with a cut or scratch.
