Q How do you finger a girl? i know the obvious bit, but like. where do you rub, does the finger actually go in? im really confused? NEED ANSWERS!!! Best Answer slowly massage the vag, then rub the clitoris ever so gently. Proceed to stick a single finger in the vagina. continue adding your fingers until your whole fist is in. slide your arm slowly into her, once you reach your shoulder limbo in with your head, and forcibly insert your other arm, torso, and legs. You are now free to control her. when you feel the job is done. finish by giving birth to yourself
