Masturbation, which used to be called masturbation, has different slang terms in each place, such as: jerking off, masturbating, etc. Because there are many different ways to masturbate, and not necessarily with your hands, masturbation is a derogatory term in Chinese, so the correct, scientific method would be masturbation. It is a normal behavior. It usually involves using your hand to stroke and stimulate your external genitals until orgasm. However, any way of touching and stimulating the genitals and other sensitive parts for sexual pleasure and satisfaction can be considered masturbation. If two people touch each other’s genitals with their hands, it should be called masturbation, not masturbation. Masturbation occurs at different ages in both men and women. Some animals also engage in masturbation. Masturbation is a behavior that has existed since childhood, mostly due to unconscious occasional play with the genitals, wearing tight pants, climbing poles and other activities where the friction of the genitals is stimulated and causes pleasure, usually without orgasm. Both men and women, after reaching puberty, due to the physiological changes in the body, hormones increase, resulting in sexual impulses and demands, full of longing, curiosity and fantasy about sexual issues. As an instinct, they will begin to masturbate consciously driven by sexual physiology and sexual psychology. That’s why masturbation is common. When people are thirsty, they need to drink water; when people are hungry, they need to eat.
