The reason why your exposure wasn't a risk is that HIV transmission is only going to happen inside a host or body. Air inactivates the virus. So, her vaginal fluid on your hand is exposed to air. You can't touch the hiv virus outside and through touching it get HIV. It just doesn't happen. So, your exposure, therefore, was no risk.
Touching someone is never a risk for HIV. You didn't have unprotected sex with her and you didn't share IV drug needles with her, therefore you had no risk.
