Durex Pleasure Ring an erect ring made of silicone improves the blood supply of a member. It makes it harder and makes it possible to enjoy sex fully, thanks to a longer-lasting erection. As a result of sensory stimulation, the brain sends signals to the penis, causing an influx of blood into the so-called penile cavity, which causes its erect tissue to fill with blood. The blood-filled penis cavity exerts pressure on the penis veins blocking the blood flow and causing erections.

It mimics this process through organic blood flow from veins in the penis and maintaining an erection.
