Men’s lower pubic hair is thick, when the body surface temperature is too high or sedentary, the thick hair will affect the heat dissipation, so that heat and sweat can not be discharged in a timely manner, thus inducing men’s lower body moisture. Or the underwear is too tight or too thick, so that the scrotum is not ventilated, the sweat secreted by the sweat glands and sebaceous gland secretion can not be discharged in time, which leads to men’s lower body moisture. When a man’s lower body has eczema conditions, resulting in increased local skin secretions, dampness, itching, flaking, rashes, breakouts and other symptoms, often accompanied by abnormal secretions, which may also lead to a man’s lower body dampness.

There are other reasons why a man’s lower body may be moist, it is recommended to avoid sitting for a long time, maintain personal hygiene, and change underwear at regular intervals.
