3 Choices for an Enhanced Erection! A cock ring is used to extend the duration of erections in order to provide more pleasure. Amp up your dick game with an easy and inexpensive way to achieve a rock-hard cock while prolonging ejaculation. Three sizes are included so that you can find the perfect fit or combine them for use together. The material is stretchy, yet firm to effectively reduce circulation, trapping blood flow in your penis. Wrap a ring around just your penis, or insert each of your testicles and then your shaft for even more effect. Not only can you last longer with a bulging erection, but it will also be hypersensitive. Sex has never felt so good! The Proper Way To Put On A Cock Ring. Many think a cock ring slips on the penis like a diamond ring; it doesn't. With a flaccid penis, slip one testicle through the ring, then the other. When the whole scrotum is in, bend and slip the soft penis through. This will push the cock ring against the body and secure it at the base of the genitals. The best way to remember is: testicle, testicle, shaft.
