rubasturbate
the combination of rubbing out and masturbating, which is to sexually exite yourself until you reach a climax. With males it involves using their hand to 'jack off', that is holding their dicks and moving their hand back and forth. Females usually use their fingers to rub around and enter the vaginal area.
