Fit and placement
- The flexible opening stretches, but stretch does not make every fit safe. Measure the location where the ring will sit and compare that measurement with the 18.5 mm unstretched opening before use.
- Depending on the intended fit, a cock ring may sit around the shaft or behind both the shaft and scrotum. Use only a placement described by the received packaging, and do not force the ring over tissue or into a position that makes removal difficult.
- The spiral exterior can add contact where it touches skin, but movement, anatomy, placement, and pressure change the feel. No specific sensation, erection change, stamina result, or partner response is guaranteed.
- Practice putting the ring on and removing it while not erect. Keep an immediate removal plan and do not stack it with another constriction product.
Conservative wear limits
- Set a timer and use 30 minutes as a maximum, not a target. Remove it sooner if the received instructions specify less time or if anything feels wrong.
- Remove the ring immediately for pain or increasing discomfort, numbness, tingling, decreased sensation, unusual coldness, marked swelling, concerning pale, blue, purple, or dark discoloration, or difficulty removing it.
- Never sleep while wearing it, and do not use it while impaired or in any situation where fit, sensation, time, and removal cannot be monitored.
- If it cannot be removed, or severe swelling, pain, numbness, coldness, or discoloration continues after removal, seek urgent medical care.
- Ask a qualified clinician before using a constriction ring if you have a bleeding or clotting disorder, reduced genital sensation or circulation, a recent genital injury or procedure, or take blood-thinning medicine.
Lubricant, care, and inspection
- A small amount of compatible water-based lubricant is the broadest starting point for placement and removal. Too much can make the ring slip. Avoid numbing products, and check compatibility with the ring and any condom or barrier before combining them.
- Clean before first use and after each use according to the instructions received with the product. If those instructions permit soap and water, use mild soap and warm water, rinse completely, and let the ring dry fully before storage.
- TPE and other elastomer formulations can vary in porosity. Do not promise sterilization; use a compatible barrier for sharing when appropriate, and do not share the ring if it cannot be safely cleaned for the intended use.
- Before and after each use, inspect for tears, cracks, sticky or swollen material, whitening, permanent stretching, persistent odor, or other surface change. Retire the ring if its condition or reliable removal is in doubt.
- Store clean, dry, separate from other soft materials, and away from direct sunlight and extreme heat.
