Top measuring tip for cock ring: With an erect penis, take a piece of string and wrap it around the base, behind the balls. Measure this string to the nearest millimeter. This will give you the circumference, so divide this by π (3.14) for the diameter. If you are between sizes, size down for a snug fit.
Size: Small: Ring Diameters 45mm x 50mm x 55mm; Large Ring Diameters 50mm x 55mm x 60mm.
