This ring features three interlocking rings: one 2 cm in diameter, one 3 cm in diameter, and one 4 cm in diameter. The largest ring should be worn around the scrotum, the second ring should be placed around the testicles, and the last one around the shaft of the penis. Wearing a ring that sits on the penis restricts blood flow and results in a fuller, harder erection, while the ring that goes around the testicles prevents them from contracting, prolonging orgasm.
