Most of the various products sold commercially to prevent male urinary incontinence have the drawback of causing urine to stain or leak and adhere to the testicles. [Solution] The present invention is an undergarment called "pleasure-relieving pants," which consists of a pant-shaped piece of fabric smaller than regular pants, with the lower part forming a pouch to collect urine. A slit is provided in the upper part, called the lower abdominal band, to allow the penis to be removed. The use of stretchy fabric such as spandex minimizes gaps, preventing the penis from easily retracting. Regarding itching relief, for small amounts of urine, such as slight stains, the urine collection bag can be made of ordinary cloth and can be used without anything inside. However, for larger amounts of urine, waterproof or water-repellent fabric should be used, and gauze, cotton wool, paper towels, absorbent cloth, or superabsorbent polymer should be placed inside the urine collection bag. If the expected amount of urine exceeds the size of the bag, the bag can be made larger and more absorbent material can be added to collect more urine, making urination easier.
