Quick answer

The Rocks Off Poseidon vibrating cock ring is a soft silicone ring with a removable bullet vibrator. To get the best fit and function, measure your girth, apply lubricant, slide the ring over the base of the penis and testicles, then adjust the bullet for targeted vibrations.

Why fit matters for the Poseidon

The Poseidon is made of soft, body-safe silicone with increasing size beads that help vibrations travel through your body. Because silicone doesn't stretch much, getting the right fit is essential: too loose and the ring won't stay in place; too tight and it can be uncomfortable or restrict blood flow. Measure your erect girth and compare it to the ring's internal diameter (not supplied, so check the product packaging or manufacturer's site) before your first use.

Using the removable bullet

The Poseidon includes a 90mm bullet with 10 vibration speeds. The bullet is removable, which means you can use the ring on its own or swap the bullet into another compatible toy. Start on the lowest speed and increase gradually to find your preferred intensity. The bullet sits in a dedicated pocket on the ring; make sure it's fully inserted before use to avoid it slipping out during play.

How to wear the Poseidon cock ring

  1. Measure your girth: Wrap a flexible tape measure around the base of your erect penis. Note the circumference. Compare it to the internal diameter of the Poseidon ring (check the product packaging or manufacturer's specifications). If you don't have the exact measurement, choose a ring that fits snugly but not tightly. If the ring feels too tight after 30 minutes, remove it immediately and try a larger size.
  2. Apply lubricant: Use a water-based lubricant on the ring and the area where it will sit. Silicone lubricant can damage the ring's silicone material. Apply enough to reduce friction during placement. Reapply lubricant if the ring starts to drag or pull on skin during wear.
  3. Position the ring: Slide the ring over the base of the penis and behind the testicles (for a full ring fit) or just around the penis shaft (for a simpler fit). The ring should sit firmly but not dig into the skin. The bullet pocket should face outward for easy access. If the ring twists or the bullet pocket rotates, remove and reposition. Never force the ring past the testicles if it feels stuck.
  4. Insert and adjust the bullet: Push the 90mm bullet fully into the pocket until it clicks or sits flush. Use the remote (if included) or the bullet's base button to cycle through the 10 speeds. Start at the lowest speed and increase gradually. If the bullet stops working mid-use, check the battery compartment for corrosion or a loose connection. Replace with a fresh battery if needed.
  5. Wear and remove safely: Wear the ring for no more than 20–30 minutes at a time. If you feel numbness, pain, or discoloration, remove it immediately. To remove, apply more lubricant and gently slide the ring off. Never yank or twist it off quickly. Clean the ring with warm water and mild soap after each use. Remove the bullet before washing the silicone ring.

Product facts
