OptiMale C Ring Kit Thin - Black

I'm picky and usually hate "one-size" stuff. This comes with three diameters and the silicone stretches well. I feel better support and I last longer than before.

Doc Johnson's silicone cock rings support long-lasting erections and help prolong ejaculation. The rings are easy to stretch around the shaft/testicles. I just wish I'd tested sizes sooner.

The ultra-stretchable silicone makes it easier to put on, but if it's not positioned right, it doesn't feel as effective. Once I got it right, support was better.

Using one ring would've been a gamble, but having 40/45/50mm makes it easy to find the right diameter. Stretch goes on smoothly. Definitely improves my experience.

The silicone is great and stretchy, and the 45mm fits me best. First time I fumbled positioning around the shaft/testicles, but after that it was smooth. Works well.
