If you're taking your first steps into the world of cock rings, then the Screaming O Vibrating Ring is a great place to start.
It's both friendly on the bank balance and on the penis. Made from silicone you're getting top quality at a great price, but it's also super stretchy and soft, offering the wearer a comfortable fit, but still providing enough blood flow restriction to prolong your erection.
Not only will you love it, but she will too thanks to the single speed vibrator on the top of the ring that will buzz against her clit on every thrust. Go on, give it a go!
