The inner diameter of your cock rings should be somewhat smaller than the diameter of your penis if they are to fit properly. In order to get the proper ring size, you need to take accurate measurements. Different regions of the penis, such as the shaft, glans, or even the balls, might be targeted by these devices.
The only place your ring should be worn is where it was intended to be worn. There are varying lengths and sensitivities across the penis, so a product that works well in one area may cause harm elsewhere.
If you experience any sensations of numbness, tingling, or discomfort while wearing cock rings, it’s best to remove them immediately.
