Fingering (stimulating the vagina with a finger or two) is not a likely
route for HIV transmission. People are primarily infected by vaginal and
anal intercourse, through sharing of needles, from an HIV positive
mother to her unborn child, and via breast milk. There is a theoretical risk of infection by fingering a woman, as
vaginal fluids and menstrual blood can carry HIV, but the virus would
have to enter your blood stream in order for you to become infected.
