Masturbation
Manual stimulation

The most common masturbation technique is to hold the penis with a loose fist and then move the hand up and down on the glans and the shaft of the penis. This type of stimulation can result in orgasm and ejaculation. The hand motion and the speed of the action may vary throughout the masturbation session. Some men may use their free hand to fondle their scrotum and testicles, the perineum, and other body parts, or may place both hands directly on the penis. Common positions include standing, sitting, lying on one's back or lying face down, squatting, or kneeling. In some cases, to avoid friction and irritation or to enhance sexual sensation, men prefer to use a personal lubricant or saliva. Men may also rub or massage different areas of their glans, like its ventral surface, the left and right sides, the rounded rim, known as the corona, and around the frenulum. Some men lie face down in prone position and gently rub their penis against a comfortable surface, such as a mattress or pillow, a technique known as prone masturbation.
