A cock ring is basically the superfood of sex toys: It pumps up your performance and enhances your pleasure in many different ways.
A cock ring can not only make your erection bigger and harder, it can also help you last longer during sex and even help your partner reach orgasm. Not to mention that it also feels pleasurable to have additional pressure and stimulation on your penis, and when you use a powerful vibrating cock ring, you experience a more full-body orgasm, with an added boost for the receiving partner.
