A handjob is the sexual stimulation or arousal of a male partner's penis by another partner using the hands. It is similar to male masturbation but it is done by someone else instead of by one's self. It is usually done by grabbing the shaft of the penis with one hand and while grabbing the shaft the hand moves up and down, repeatedly retracting the penis until the male reaches orgasm. Stimulation of the scrotum may also be accompanied. It is like fingering which is the sexual stimulation of a female's genitals using the hands and fingers.
