You did not have any risk. Even IF the stripper had vaginal secretions on her hand and touched your scratch, HIV cannot infect that way for a few reasons.
One, the virus does not remain active outside of the body, and two, the virus would have to make it to the bloodstream to allow for infection, which would not happen with a superficial scratch or cut. The skin is comprised of many protective layers, so the virus would not have a way to reach the bloodstream.
Put this worry behind you, it was not a risk.
no at all & no whatsoever :)
