The Earl is a Mystim cock ring made of 100% surgical stainless steel, and he is not just an erotic piece of jewelry: He can also help you have longer and more intense sex.
Finding the right size is crucial in order to guarantee the best results of a cock ring: If the ring is too big, it doesn't do the trick, or might even fall off. If a ring is too small, it might lead to medical problems. Therefore please always insure that a cockring fits tightly, but is neither unpleasant nor painful at any time. Measure the right size by wrapping a piece of non-elastic band around the testicles and penis, so that the ends of the band meet on top of the penis, close to the body. Pull the band tight, so that it feels still comfortable. Mark the band on both sides, where the ends meet and measure the length in mm. Now divide this length by pi (3.14) in order to find out your diameter. We recommend repeating this measurement on some days and various day times because there might occur natural fluctuations.
Start by carefully tucking in one testicle at a time and then insert the penis into the ring. Never wear the cock ring for more than 30 to 35 minutes and always remove the ring gently if needed using a lubricant.
