Cock rings inhibit blood flow, which may help make his erection larger and harder, for longer, and is fully reusable. Cock rings can come in many different types of materials (some stretchy, some are hard like chrome or stainless steel which are for more advanced users). Cock rings can also have a vibrating component allowing sensations to flow through to both parties during intimate play. It is recommended that cock rings are not used for more than 20 minutes at a time.
Metal cock rings are only recommended for experienced users as they generate much more constriction than those made from softer, more flexible materials, resulting in a much more intense sensation. Metal cock rings cannot be stretched and pulled off or cut off if you want to remove them in a hurry, so you must be sure of how to use a metal cock ring.
Be sure to measure yourself for the right fit. A tighter ring will lead to a firmer, longer-lasting erection, and a more intense ejaculation. Some men find a tighter fit uncomfortable, while others enjoy it, so you do research and should try a variety to explore your preferences.
In order to ensure a good fit with a metal cock ring, you must measure the base of the erect penis. Wrap a piece of string around the area (Ensure fit is snug and not too tight or too loose), and then measure the length of that piece of string. This gives the circumference of the ring. Divide this by 3.14 to give the diameter.
As an example, if the circumference of the erect penis is 90mm, then 95 / 3.14 = 30.25mm.
You should then find the ring size that is closest to you. Choose carefully as a cock ring with a diameter larger than the erect penis' diameter may be too loose to generate restrictive blood circulation whilst on the other hand if the ring is too small, then it may be too uncomfortable for wear.
If you are unsure about the measurements, consider using a ring with snaps or a stretchy ring which makes exact sizing much less of an issue and, you can easily take or cut off if you experience pain or discomfort.
