Ram Beaded Cock Rings in Black A fantastically versatile trio of extra soft, super-stretchy erection rings from Nasstoys, the Ram set offers three plush possibilities, each with a size and texture all its own. The largest ( 1 1/2 inches un-stretched) is intended for cock and ball constriction, fitting snugly around both the base of the penis and the testicles. A more advanced level of constriction becomes possible with this type of ring, and many men swear by C&B rings as a way to delay ejaculation. The mid-sized ring (1 1/4" un-stretched) )is also the thinnest and least textured, providing a less intense feel, the smallest boasts another 1.19 inches and for more extreme hold.
