Boneyard Silicone Cock Ring Black 35MM by C1R Releasing

Boneyard Silicone Cock Ring Black 35MM by C1R Releasing is a medical-grade silicone ring made to restrict blood flow and maintain harder, longer-lasting erections. The seamless 35mm diameter fits most men comfortably and works during solo or partnered sex. It stretches on easily and snaps back to provide consistent pressure throughout wear.

What you're getting

Boneyard Silicone Cock Ring Black 35MM by C1R Releasing is a fixed-size ring engineered to deliver reliable performance through medical-grade silicone and precision manufacturing. The 35mm diameter sits at the midpoint between aggressive restriction and all-day comfort, making it a practical choice for men who know their sizing. Unlike cock rings with adjustable closures or snap mechanisms, this one is seamless—no seams, no joints, no pressure points where materials meet.

The silicone stretches smoothly during application but holds its shape and tension once positioned. Waterproof construction means you can wear it during shower sex or in water without degradation. The smooth surface resists irritation, and the material maintains consistent firmness across temperature changes and extended wear sessions.

Features worth knowing

• Seamless silicone body: One-piece construction eliminates weak points, seams, and the pressure spikes that cause discomfort or early fatigue.
• 35mm precision diameter: Sized to suit most adult men—restrictive enough to improve erection quality without cutting off sensation or becoming painful with time.
• Medical-grade material: Body-safe silicone means no harmful chemicals, no allergenic reactions, and no worry during extended wear or sensitive skin contact.
• Waterproof and temperature stable: Performs consistently in showers, baths, or changing body heat without losing elasticity or structural integrity.
• Easy application and removal: Stretches on smoothly and snaps back to working tension, so you can put it on without fumbling or tugging.

Getting the fit right on a silicone cock ring

Start by measuring or testing the fit before your first full session. Slip the ring on when your penis is flaccid or semi-erect—this is when it's most flexible and easiest to position. Slide it down to sit snugly around the base, just above the testicles. The fit should feel secure but not pinching; you should be able to fit one finger underneath comfortably. Once positioned, achieve or maintain an erection—you will feel the ring working immediately as it restricts outflow and firms your erection.

Wear time builds gradually. Start with 15–20 minutes to let your body adjust to the sensation and pressure. Most users extend to 30–45 minutes as comfort improves. Remove the ring if numbness, colour change, or sharp pain develops—these are signs you need a looser fit or shorter duration. Many men find that wearing time varies with arousal level and partner activity. Silicone offers more forgiveness than metal, but Gates Of Hell C-Rings and other fixed designs demand stricter attention to fit, so start conservatively with this ring too.

Is this the one for you?

Care and storage

Wash the ring with warm soapy water after each use and pat dry thoroughly with a soft cloth. Store it in a cool, dry place away from direct sunlight, which can degrade silicone over time. Keep it separate from other silicone toys, as some silicone formulations can interact. Avoid prolonged contact with petroleum-based lubricants, which can soften medical-grade silicone; water-based or hybrid lubricants are safer choices. Inspect the ring periodically for signs of tearing or discolouration.

What to expect

Most first-time users notice a firmer erection within moments of putting the ring on. The sensation is usually a mild, pleasant squeeze at the base—not painful if the fit is right. Some men feel a subtle warmth or fullness as blood pools in the penis; others describe heightened sensitivity. Your erection will feel noticeably harder and may last longer than usual, even after orgasm. Expect a brief adjustment period as your body acclimates to the new sensation.

Removal can sometimes require a gentle wiggle or slight stretching of the silicone, especially if you have worn the ring for an extended period or achieved a very full erection. Flaccidity makes removal much easier, so it helps to wait a few minutes after climax or to reduce stimulation briefly. The silicone will not tear or degrade from normal removal, but avoid yanking or forcing it.

Silicone rings like this one suit men who appreciate comfort over maximum restriction. If you are seeking more aggressive blood flow restriction or a longer wear time before fatigue, metal or harder materials may deliver it—but they also carry higher irritation risk. Most users find this ring strikes a practical balance for sessions lasting 20–45 minutes and appreciate the low maintenance and skin-friendly material.
