What is more effective- Wearing a ball zinger or penis ring?? Both make you develop a better ejaculation level, higher testosterone level, and bigger testicular/penis size. Supposably the penis ring increases penis girth because the amount of blood that is being trapped into the penis. But the ball zinger apparently increases the size of your testicles and penis. So if im using a ball zinger/penis ring and i have a normal testosterone and ejaculation level would that be dangerous?
