Stainless steel cock ring (2.8cm inner diameter·1.5cm high)

A stainless steel ring worn at the base. It is a metal ring with a 2.8cm inner diameter, a 3.8cm outer diameter and a height of 1.5cm, and it works by holding back the blood flow at the base to help maintain an erection for longer.

The size in numbers

An inner diameter of 2.8cm is about the space two fingers take up. The difference between the inner and outer diameters is 1cm, so the wall of the ring is 0.5cm on each side, and at 1.5cm high it counts as a wide one. A wide band keeps the pressure from concentrating at one point, so it digs into the skin less than a thin ring does. Being metal, it feels cool at first and soon warms to body temperature.

What a metal ring means

Unlike a silicone ring, it does not stretch. That means the size has to be right from the start, and once it is on, it only comes off after the erection subsides. In exchange, the shape never changes, so the pressure stays consistent and it will not slacken and go loose with use.

Before you use it

The ring does not stretch, so measure first and see whether 2.8cm across the inside suits your body. Forcing it on makes taking it off harder still. Wear it in short stretches and do not keep it on while you sleep. If the area goes numb or the color darkens, take it off immediately, and a little water based lubricant makes it easier to get on and off.
