Urethral play demands precision, trust, and a device built for control. The Tunnel Penis Plug delivers intense sensations through medical-grade stainless steel engineering, letting experienced users explore deep stimulation safely and confidently.
The Tunnel Penis Plug is a precision urethral device engineered for experienced users seeking controlled, intense stimulation. Manufactured from 316 medical-grade stainless steel, it features a hollow core design and tapered profile that progresses from 7mm to 12mm diameter. This graduated approach allows gradual insertion while building sensation safely. The movable glans ring keeps the plug secure during extended wear and movement.
What sets this plug apart is its hollow construction, which permits urination during wear and opens new dimensions for extended play scenarios. The stainless steel is non-porous, hypoallergenic, and easy to sterilize, making it genuinely body-safe for intimate use. See the full BDSM Australia range of Penis Plugs to explore other options in this category.
Start by cleaning both the plug and your genital area thoroughly. Apply water-based lubricant generously to the tapered tip. Relax your body and breathe deeply as you slowly guide the plug inward, allowing the tapered design to lead the way. Work at your own pace—there is no rush. Adjust the movable glans ring once the plug is positioned for comfort and optimal stimulation.
Extended wear becomes possible thanks to the hollow core design, which permits normal urination throughout your session. Experiment with different insertion depths and angles to discover sensations that resonate with your body. Explore Tunnel Plugs in various styles to find what suits your experience level. Temperature play—warming or cooling the steel beforehand—can intensify sensation. Always listen to your body and stop immediately if you experience pain or discomfort.
Clean The Tunnel Penis Plug immediately after use with antibacterial toy cleaner and warm water, paying special attention to the hollow core. Sterilize by boiling for 3–5 minutes or using medical-grade sterilization solutions. Dry completely before storage. Keep the plug in its provided pouch in a cool, dry place away from direct sunlight and extreme temperatures to preserve the stainless steel finish.

The Tunnel Penis Plug is one of my most effective control tools. Its weight and hollow design allow me to maintain dominance throughout extended scenes, watching my submissive's psychological surrender deepen with each moment. Cold stainless steel against sensitive tissue becomes a powerful trigger—fear transforms into exquisite vulnerability.
My technique begins with gradual insertion, using the tapered design to map my submissive's boundaries. I monitor their breathing and expressions carefully, adjusting pace based on their psychological landscape. The movable glans ring gives me precise control over positioning and sensation intensity. Combining The Tunnel with sensory deprivation creates unprecedented levels of trust and submission.
Extended wear scenarios amplify the psychological impact dramatically. Knowing the plug permits urination means scenes can stretch for hours, deepening my submissive's sense of control loss and my dominance. Some require gentle coaxing; others crave immediate intensity. The hollow core's unique properties open power exchange possibilities unavailable with solid devices.
