In our experience cock rings can sometimes serve as a(n unnecessary) distraction. Sometimes, however, they can politely take a backseat to the action and serve as a subtle enhancement: namely, priming that dick until it's firm, full and ready to blow.
It's a remarkable wonder, the extra stamina that comes from this backseat encouragement. We imagine it walks that line between exquisite pleasure and the staving off of pain. We have extreme empathy for this soldierly cock, but... since we're just watching, we'll go ahead and go with the pleasure route for ourselves, thanks.
