Rest easy. This was not a risk for HIV. One condom is all that is necessary by the way and experts say to ONLY use one condom. But you used a condom none the less, so were protected. Only the tip of your penis needs to be protected and it was. The ONLY risks for HIV are to have unprotected vaginal or anal sex or share IV needles to inject drugs. Air inactivates the virus. A cut on your finger when fingering is NO risk at all. You can't get hiv from fingering. So, you had no risk at all.
