Cock rings (penis rings or c-rings) are often thought of as just something to wear, but that also deflects how cock rings can enhance any man's sex life. Cock rings can help you maintain stronger erections; they can even be used when you struggle to get an erection in the first place. They can also make you last longer (particularly when the rings constrict your testicles).

Which cock ring is best for you? Rock Solid has a variety of male enhancing cock rings ready for you to try. We present a wide variety of cock rings in terms of price, shapes, penis, and testicle placement, so there's definitely a cock ring that is right for you.

Rock Solid cock rings combine quality and comfort for your best performance.

A cock ring or cockring (also called C rings, erection rings, penis rings, shaft rings, or tension rings) is worn around the penis, usually at the base. The primary purpose of wearing a cock ring is to restrict blood flow from the erect penis to produce a stronger erection or maintain an erection for a more extended period. Genital adornment is another purpose, as is repositioning the genitals to provide an enhanced appearance.

Cock rings are also called C rings, penis rings, or shaft rings. When used in cases of erectile dysfunction(ED), they are known by various other names, such as erection rings and tension rings.

Cock rings worn just behind the corona of the glans of the penis are known as glans rings, head rings, or cock crowns. A ring worn around the penis and scrotum is usually called a cock ring but is sometimes referred to as a cock and ball ring. Rings worn just round the scrotum to hold the testicles are typically called testicle cuffs or ball stretchers.
