What it does

Hollow construction creates a dual sensation you won't find in solid sounds. You feel both the internal pressure of the steel sitting inside your urethra and the natural flow when you orgasm or pee—no removal needed. As you move during arousal, the insert shifts subtly, creating focused friction along nerve pathways that standard plugs miss entirely. Penis Plugs come in many designs, but this hollow core delivers a unique experience somewhere between controlled expansion and shifting pressure.

Temperature play amplifies everything. Chill the steel in cold water for sharp contractions that make your penis hypersensitive, or warm it gently for relaxing pressure that lets you wear it longer during sessions. Stainless steel holds temperature exceptionally well, so the sensation you choose stays consistent throughout play. Movement during masturbation builds sensation gradually rather than delivering one static feeling.

Size and first use

At just 2.54mm diameter, this insert suits both newcomers to metal sounds and experienced players who prefer focused sensation over stretched feeling. Start with thorough cleaning of both yourself and the insert, then apply sterile lubricant designed specifically for urethral play. Insert slowly and let your urethra adapt to the steel's presence—the ball stopper prevents over-insertion automatically. Cockringshop specialises in products for men and couples exploring sounding safely, so take your time with the first session and don't rush deeper than feels comfortable.

How to use it

Once positioned, you can wear the insert during masturbation or leave it in place for extended sessions. Movement creates shifting sensations that build gradually. You maintain full function—the open channel means you can climax without removing it, or urinate if needed. Intensity grows as arousal increases rather than staying flat throughout wear.

Remove slowly after play and clean immediately with appropriate hygiene practices. Maintaining cleanliness is essential for any urethral sex toy. Rinse thoroughly and allow to dry completely before storage. Regular sterilisation between uses keeps the steel in safe condition for extended wear sessions.

Feature breakdown

Feature Specification Benefit Experience
Hollow Core 2.54mm internal bore Maintains function during wear Pressure without complete obstruction
Ball Stopper Flared base design Prevents over-insertion Confident deep play
Steel Construction Medical-grade stainless Temperature responsiveness Warming and cooling sensations
Smooth Finish Polished surface Comfortable insertion Reduced friction irritation

Who it suits

Perfect for sounding enthusiasts who want functional versatility beyond basic stimulation. If you enjoy longer sessions or need the option to climax without removal, this hollow design solves practical concerns while intensifying sensations. Players who prefer focused rather than stretched sensations will appreciate the narrow diameter. Both newcomers mastering basic sounding safety and experienced players find value in the metal's temperature responsiveness and subtle shifting feel.

Skip this if you have any urinary tract issues, active infections, or haven't yet mastered basic sounding safety fundamentals. Rough play isn't suitable for this insert. Don't share between partners without complete sterilisation between uses. This requires absolute cleanliness and solid understanding of proper insertion techniques—it's not a casual sex toy.

Tested and quality-checked

Every new line we stock is hands-on tested before it ever goes live — we power it up, run it through its functions, and check it for safety and for how it actually performs. Overseas orders get a second function-test right before they ship, so a dead motor never reaches your door. Nothing is used for its intended purpose; it is checked, inspected, and re-boxed. What that means for you is simple: the unit you open is one we already know works. See how we test every product →

How it compares

Solid urethral sounds deliver static stretching sensation, whereas Hollow Penis Plugs like the Chasm let you maintain function while wearing. Hollow designs shift during movement and create internal pressure rather than external stretch. Stainless steel is rigid with no give, holding its shape and temperature consistently—different from flexible silicone or softer materials that conform to your body. This insert's conductive steel also pairs with electrostimulation if you explore that direction later.

Please read — safety first. Put the ring on before you are fully erect and use plenty of water-based lubricant so it slides on without pinching. Keep wear time short — no more than 20 minutes while you are getting used to it, and never fall asleep wearing one. Take it off straight away if you feel numbness, coldness, a change in colour, or any pain, as these mean blood flow has been cut off too far. Never share between partners without cleaning the item first or using a fresh condom. This information is general in nature only and is not medical or professional advice, and does not take your personal circumstances into account. Stop use and speak with a qualified medical professional if you have a relevant health condition, take medication for erectile function or blood pressure, or notice pain, numbness, or discolouration that does not settle.

What you can use it with

Pair the Chasm with Anal Sex Toys for full-body internal stimulation during solo or partnered sessions. While the insert focuses on urethral sensation, complementary anal play creates layered pressure and sensation across different nerve pathways. The combination builds more complex arousal patterns than either alone, and the hollow design means you can still climax without removing either sex toy.
