MYSTIM THE DUKE - EDGED COCK RING, 55 MM, POLISHED

The Duke is a 100% surgical stainless steel cock ring that is not only a piece of erotic jewelry but can also help you have sex for longer and with more intense sensations!!!!!. Finding the right size is crucial to ensure the best results. If the ring is too big, it doesn't press, therefore it won't do its job and may even fall out. Conversely, if the ring is too small, it can cause medical problems. You have to make sure that the ring fits your penis tightly, without having any symptoms of pain or discomfort. You can find out the size you need by putting a band around your testicles and penis, so that the ends of the band meet at the top of your penis, close to your body. Then pull the band, feeling comfortable with the measurement. 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 its diameter. We recommend repeating this measurement for a few days at different times as natural fluctuations may occur. If you are new to rings, when in doubt always choose a larger ring. Never put the ring on the erect penis. Start with the testicles first and then insert the penis. Never use it for more than 30 minutes at a time and if necessary use lubricant for better removal.
