What it is

The Tantus Silicone C-Ring 1 7/8 Inch Black is a fixed-diameter cock ring made from medical-grade silicone. It works by gently restricting blood flow at the base of your penis, helping you achieve and maintain firmer erections. The non-stretch design keeps consistent tension, so you get reliable performance every time you wear it. Unlike rings that stretch unpredictably, this one delivers the same level of restriction across multiple uses.

What sets it apart is its broad, evenly-weighted construction. That design distributes pressure across a wider area, reducing discomfort while maximizing the blood-flow effect. It's hypoallergenic, phthalate-free, and safe for extended wear during solo or partnered sex. See the full BDSM Australia range of Stretchy Cock Rings to compare other options.

How to use a stretchy cock ring

Stretch the ring gently and slide it over your penis and testicles, positioning it at the base of your shaft. Adjust until it feels snug but not painfully tight—you should be able to fit a fingertip between the ring and your skin. Start with shorter wear periods of 10–15 minutes, then gradually extend duration as your body adapts to the sensation.

During sexual activity, the ring restricts blood flow, helping you maintain a harder erection and delaying climax. You can wear it during masturbation to explore different levels of sensation and experiment with orgasm control. Pair it with Cock Straps for added support and enhanced restriction if you want to intensify the effect further.

Always use water-based lubricant, remove the ring immediately if you experience numbness or pain, and limit wear to 30 minutes or less to maintain healthy blood circulation. 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

Clean the ring thoroughly after each use with mild soap and warm water, then pat dry. For complete sanitization, boil it for 3–5 minutes and let it cool completely. Store in a cool, dry place away from direct sunlight and heat. Avoid silicone-based lubricants, which can degrade the material over time.

Mistress Athena's training notes

This cock ring is one of my go-to tools for control and denial. The fixed diameter means I can rely on consistent restriction every time I place it on a submissive. Watching their breathing shift as blood flow tightens—that moment of surrender—tells me everything about their headspace. The silicone feels substantial in my hand, a physical reminder of my authority.

I use it strategically during edge training. A submissive wearing this ring becomes acutely aware of every sensation, every touch, every command. Remove it at the wrong moment, and their frustration deepens beautifully. Apply pressure at the right moment, and their entire body responds. The psychological power is as important as the physical effect.

Extended wear scenarios reveal interesting responses. Some submissives develop a quiet desperation after 20 minutes of constant tension. Others enter a meditative state, fully focused on my voice and instructions. The ring becomes a symbol of my control—simple, effective, and impossible to ignore.

See this and similar tools in action across my 300+ training videos on the BDSM Australia channel.
