Ball stretchers are designed to lower your sac and balls. There are many people who like the look of low-hanging testicles so they use these ball stretching devices to elongate their scrotum. With a long scrotum, you get low-hanging balls. The feeling of stretching and wearing ball weights also feels very pleasurable and erotic to many people. Finally, some users like ball stretching devices because they are great for BDSM play or even cock and ball torture (CBT). However, it is important to know that testicle stretchers are not torture devices per se: they are, in fact, very comfortable. Just make sure to use a proper testicle stretcher that is safe for the body.
