Itching and uneasiness occur on the penis after consuming spicy or outside food. This discomfort is relieved by drinking 6-8 liters of water and usually subsides within 3-4 hours. The same symptoms appear when daily water intake is low (around 2-3 liters). Additionally, a similar reaction occurs after the first instance of sex or masturbation,drinking 1 bottle beer requiring a high intake of water to return to normal.
