A metal cock ring is a luxurious sex toy that will prolong the erection. The ring makes sure the blood stays in the penis, so it stays erect for a longer period of time. The glans will also become more sensitive and the whole penis will swell up. This metal cock ring from the Sinner Gear collection is available in various sizes and can be worn around both the penis and the balls. All metal sex toys can be used in combination with any type of lubricant for worry-free pleasure.
