The Kinky Monster cockring made of stainless steel in a donut shape is the most popular metal cockring. Donut shape means that the ring is wider than it is thick. This cock ring has a width of approx. 20mm and a thickness of approx. 10mm. The erotic piece of jewelry for men ensures longer and more intense sex, but metal cock rings are unsuitable for beginners. Never put on the cock ring when the penis is erect. Insert one testicle at a time and finally the penis. Do not wear the cockring for longer than 30 minutes and simply remove it with a lubricant. How do you find the right size for you? Measure the circumference around the testicles and tail with an elastic band and divide the length in mm by pi (3.14) to determine the required diameter. It is best to take several measurements at different times of the day. If in doubt, choose the larger diameter. The weight of this cockring is an impressive 150g, which means you will definitely feel it when you wear it. The Kinky Monster Cockring is available in 4 different inner diameters: S=35mm, M=40mm, L=45mm, XL-50mm.
