A cock ring is a ring that is placed around a penis at the base to slow blood-flow from the erect penis. Cock rings are used to maintain longer erections and for delayed orgasm. Cock rings can be worn around just the penis, the scrotum, or penis and scrotum.
A cock ring can be made of leather, rubber, or silicone, though nylon and metal, with leather being the most popular.
Some models include a protruding clitoral stimulator, designed to tickle the clitoris, vulva or anus during sex. Others, such as the Vibrating ring, vibrate, either vibrating the ring itself, or in a popular 'Dolphin' variant using two removable bullet vibrators to provide stimulation to the testicles and clitoris.
Some cock rings have vibrators attached which can be worn to stimulate the scrotum or perineum or a partner during sexual intercourse. Another variation is an inflatable cock ring for added control of adjustment.
Many women find rings with vibrator attachments provide clitoral stimulation and some men enjoy using cock rings for masturbation. Wearing of this sex toy provides better erections and delays orgasm, intensifing orgasm. Also vibrating cock rings deliver a great range of very pleasurable vibrations that enhance enjoyment.
A triple cock ring or triple crown is a cock ring that has additional rings for restraining the testicles. In orgasm, the testicles usually retract towards the body before ejaculation. A triple crown changes and intensifies the sensation of orgasm by forcing the testicles to stay away from the body.
