One benefit of using a cock ring and ball stretcher is that they can help to increase the size of the penis. The cock ring works by constricting the blood flow in the penis. This causes the penis to fill with more blood, which makes it more prominent and firmer.
The ball stretcher works by stretching the scrotum. This causes the testicles to descend lower in the scrotum, which makes them appear larger.
Another benefit of using a cock ring and ball stretcher is that they can help to increase the duration of erections. The cock ring prevents blood from flowing out of the penis, which helps to keep the erection longer. The ball stretcher prevents the testicles from retracting into the body, which also helps keep the erection longer.
It is essential to ensure that the devices are made of body-safe materials. The devices should also be the right size. The devices should be tight enough to be effective but not so tight that they cause pain or discomfort.
