The Screaming O's RingOs are one of the most popular style of stretchy cock ring thanks to their simple yet very effective design. These super-stretchy cock rings have just one purpose: to keep your erections long, strong and hard until the job is done. The snug fit is what helps restrict blood flow to the penis. You may notice increased sensitivity, a heightened sense of pleasure, and some RingOs wearers experience more powerful orgasms. RingO’s are also reusable – just give them a wash with soap and warm water and it's good to go.
