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.
