Cock rings have long been a favourite of men everywhere. They can either be worn on the cock itself or behind the balls. One of our most popular types are mens metal cock rings. These cock rings are solid and unlike their rubber counterparts have no give in them. This restrictive nature means they can be perfect cock and ball torture devices. Mens metal cock rings are most often used to enhance and prolong his erection. This obviously has the direct benefit of making sex last longer and hopefully more enjoyable for both partners. Wearing a cock ring behind the balls has the effect of pushing them up and making them more pronounced.
