What’s so great about cock rings? For one, they feel really good. They’re also a non-pharmaceutical solution for Erectile Dysfunction. Rings help keep erections stronger for longer by squeezing to restrict blood outflow. Many hetero couples use them to provide clitoral stimulation (and the vibrations feel great on the penis too). Made using medical grade body silicone. Comes with a 3 year warranty. Lasts for one hour continuous play. USB rechargeable and 100% waterproof.
