What it is

ScreamingO The Big O is a vibrating cock ring engineered for couples who want dual stimulation during partnered sex. The ring stretches around your penis and testicles, creating a snug fit that maintains erection while nine distinct vibration patterns deliver sensation to both partners. Made from body-safe SEBS—a hypoallergenic synthetic rubber—it's free from latex and phthalates, making it safe for sensitive skin.

What sets this ring apart is its waterproof design and straightforward control system. You can switch between nine vibration modes and a steady pulse, letting you customise intensity in the moment. See the full BDSM Australia range of Cock Rings to compare other styles and materials.

How to use a cock ring

Start by stretching the ring over your penis and testicles, positioning it at the base so it sits snugly but comfortably. Insert the battery into the ring's battery compartment and press the power button to activate it. Cycle through the nine vibration patterns using the control button until you find a setting that feels right, then adjust as arousal builds during foreplay or penetration.

Communicate with your partner about which patterns she enjoys most, and don't hesitate to switch modes mid-session to keep sensations fresh. The ring maintains erection and reduces sensitivity, so you'll last longer while she receives direct clitoral stimulation from the vibrations. Explore Hydro Cock Pumps if you want to combine cock ring use with other enhancement techniques for even greater control and sensation.

Always apply water-based lubricant before putting on the ring, wash it thoroughly with warm water and soap after each use, and remove it immediately if you experience numbness or pain in the penis or testicles. Safety first. This information is general in nature only and is not medical or professional advice; it does not account for your individual circumstances. Discontinue use immediately if you experience pain, numbness, discolouration, irritation or discomfort, and seek advice from a qualified medical professional if you have a relevant health condition or if symptoms persist.

Care and storage

Wash the ring under warm running water with mild antibacterial soap after every use, paying attention to seams and crevices where bacteria can hide. Pat it dry with a soft cloth and allow it to air-dry completely before storing. Keep it in the provided drawstring bag, away from direct sunlight and extreme heat. Replace the battery when vibrations weaken, and store fresh batteries in a cool, dry place.

Mistress Athena's training notes

This cock ring has become indispensable in my scenes requiring sustained arousal and psychological control. When fastened around a submissive's penis, it transforms his entire sensory landscape—the vibrations create physical responses he cannot suppress, breaking down his mental defences. I use the nine patterns strategically: a slow pulse during bondage work builds anticipation, while faster rhythms during denial scenes amplify his frustration and compliance.

The ring's versatility allows me to reward or punish through vibration alone. A submissive locked in chastity for days responds to even the gentlest pattern with visible desperation. I've observed that controlling the intensity becomes a form of psychological dominance—he learns that obedience earns pleasure, disobedience brings silence. The waterproof design lets me incorporate it into sensory play scenarios without equipment limitations.

What makes this ring particularly effective in my practice is its ability to sustain arousal without ejaculation. During extended training sessions, I can keep a submissive on edge for hours, cycling through patterns to prevent habituation. His psychological surrender deepens as physical sensation and mental submission intertwine. By the end of a scene, the ring has become an extension of my control—a tool that speaks my commands directly through his body.
