Urethral play demands precision, safety, and materials you can trust. The Chasm Stainless Steel Cum-Thru Insert delivers all three—a hollow, medical-grade steel plug engineered for advanced users who want intense sensory exploration with the ability to urinate and ejaculate during wear.
The Chasm Stainless Steel Cum-Thru Insert is a precision urethral plug built from hypoallergenic, medical-grade stainless steel. Its hollow construction sets it apart—you can urinate and ejaculate while wearing it, creating sensations traditional solid plugs cannot deliver. The ultra-slim 0.10-inch diameter and smooth, polished surface make insertion controlled and manageable for experienced users. Stainless steel's non-porous nature means thorough cleaning and sterilization are straightforward, and its temperature conductivity opens doors to temperature-play exploration.
This is a tool for advanced urethral play, not an entry point. See the full BDSM Australia range of Penis Plugs to compare styles and find what suits your experience level. The Chasm rewards patience, proper lubrication, and respect for your body's limits.
Start by thoroughly cleaning the insert with antibacterial toy cleaner and warm water. Apply generous amounts of sterile, water-based lubricant to the urethra and the insert itself. Insert slowly and deliberately, allowing your body time to adjust. Stop immediately if you experience sharp pain—discomfort signals you need more lubrication or slower progression. Never force insertion.
Once inserted, you can urinate and ejaculate normally thanks to the hollow design. Explore temperature play by warming or cooling the steel before use. Pair the insert with other equipment like Penis Gags for layered sensory control. Always remove gently, clean thoroughly, and listen to your body. Advanced users may extend wear time, but begin with short sessions to build tolerance safely.
Clean the insert immediately after use with antibacterial toy cleaner and warm water. For complete sterilization, boil for five to ten minutes or use medical-grade sterilization solutions. Dry thoroughly before storage. Keep the insert in the provided storage bag away from direct sunlight and extreme temperatures. Water-based lubricant only—oil-based products can degrade certain materials over time.
Understanding urethral anatomy and best practices makes safer, more rewarding play possible. Read Penis Plug Information for detailed guidance on insertion techniques, safety considerations, and how to recognize when your body needs a break.
The Chasm Insert grants me absolute control over a submissive's most sensitive territory. When introduced carefully, it creates psychological surrender that few other tools match. Watching a submissive tremble as I guide the insertion—knowing they are completely vulnerable to my direction—reinforces the power dynamic instantly. The hollow design permits extended wear, which deepens their awareness of my control throughout a scene.
Technique matters enormously here. Some submissives require gradual introduction with extended lubrication and patience; others respond to more direct insertion once they understand the sensations involved. I monitor breathing and micro-expressions constantly, adjusting pressure and speed accordingly. The insert becomes a psychological anchor—a reminder that I command even their most intimate functions.
Temperature play amplifies the psychological impact significantly. Warming the steel before insertion heightens sensation and anticipation. Cooling it shifts the sensory profile entirely, keeping the submissive uncertain and attentive. This unpredictability deepens their submission. I always emphasize aftercare following extended wear, as the psychological intensity can be profound.
