Mystim cock rings made of 100 percent surgical stainless steel are not just erotic pieces of jewellery. They can also help you have longer and more intense sex. Never put on the cock ring on an erect penis. 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.
