The skin outside the genitals is sensitive to stimuli of the opposite sex, and sensitive same-sex excitations maintain reflex connections. These parts of the human body are called sexy regions. The meaning of the sexy area is to receive stimulation from the opposite sex, enhance sexual excitement, and promote sexual behavior. There are significant differences in the sexual appeal areas between men and women.
Due to the active nature of men during sexual activity, their sexual areas are narrow and concentrated. The male sex appeal area is also divided into three parts, from strong to weak.
The first part focuses on the sexual organs, including the neck of the penis, the coronal sulcus, and the frenulum of the penis, as well as the skin of the penis body located directly below the glans penis, especially the skin that travels along the urethra.
The second part is the area around sexual organs such as the scrotum, perineum, and inner thighs. The skin between the anus and scrotum, as well as the skin between the scrotum and inner thighs, is sensitive to soft touch.
These parts are also highly sensitive to sexual stimulation, second only to the first part.
The third part is a part of the chest and lips and fingers. The sexual sensitivity of the lips can be demonstrated through kissing. The sensitivity of fingers is particularly strong in males, as touching a woman's body during contact can generate strong sexual excitement.
The dominance and aggression of men in sexual life are usually bridged by the sensitivity of their fingers.
As elderly men age with the physiological aging of various systems throughout the body, the reflexivity of the nervous system and the sensation of skin irritation also decline with age. The sensitivity of the skin in the sensitive area to sexual stimulation decreases compared to when young, and the threshold for sensory stimulation required for sexual stimulation also increases. The changes in physiological characteristics of these sexy areas may be one of the reasons for the slow response of elderly men.
