Cockrings

Cockrings can be a great addition to healthy love-making, as they can help to maintain an erection, as well as making an erection harder than usual. They work by restricting blood-flow out of the penis. Cockrings are especially useful if you are able to achieve an erection, but can't keep it hard for long. As they stop the blood flowing back into the body, you'll achieve longer-lasting erections.
