Glowstick Jewelled Ascending Penis Plug Diamond

Urethral play demands precision and control—ordinary plugs lack the refinement needed for advanced stimulation. The Glowstick Jewelled Ascending Penis Plug Diamond delivers progressive stretching with medical-grade stainless steel, letting experienced users explore intense internal sensation safely.

What it is

The Glowstick Jewelled Ascending Penis Plug Diamond is a precision urethral sound engineered for advanced internal stimulation. Built from medical-grade stainless steel with a mirror-polished finish, it features a gently ascending design that stretches from 7mm to 13mm diameter over its 35mm insertable length. The diamond-like jewel accent serves both as a visual focal point and a convenient handling grip. Its smooth, non-porous construction makes cleaning straightforward and compatible with temperature play—warm or cool the steel before insertion for enhanced sensory variation.

This plug stands apart through its precise engineering and aesthetic refinement. Medical-grade stainless steel eliminates allergenic concerns while delivering the smooth, body-safe experience advanced users expect.

How to use a penis plug

Start by washing your hands and the plug thoroughly with antibacterial soap and warm water. Apply generous amounts of sterile water-based lubricant to both the urethral opening and the plug's tip. Relax completely, breathe steadily, and gently spread the urethral opening with your fingers. Slowly introduce the plug's tapered tip, allowing your body time to adjust to the progressive width. Move at your own pace—any discomfort is a signal to pause or withdraw.

Once inserted, you can explore gentle movement or hold the plug stationary while focusing on internal sensation. Many users find that combining the plug with external stimulation or controlled breathing deepens the experience. For added sensation, try warming or cooling the steel beforehand. Pairing this plug with Penis Pouches can extend comfort during extended wear. Always communicate openly with partners, prioritise consent, and never force insertion beyond your comfort threshold.

Care and storage

Clean the plug immediately after use with warm water and antibacterial soap, paying attention to any textured areas. For complete sterilisation, boil in water for 5–10 minutes, then allow to air-dry on a clean cloth. Store in a dry, dust-free location away from direct sunlight. Inspect the surface before each use for any scratches or irregularities. Use only water-based lubricants to protect the stainless steel's integrity.

Mistress Athena's training notes

By Mistress Athena — professional dominant and kink educator, sole instructor behind BDSM Australia's library of training videos. Read her full bio →

This plug's ascending design gives me remarkable control over my submissive's responses. The diamond accent catches light beautifully—a visual reminder of dominance that intensifies psychological surrender. Watching anticipation build as I slowly advance each millimetre, observing their breathing shift from resistance to acceptance, demonstrates the power of precision play.

Cold steel creates immediate physiological response before insertion even begins. My technique involves holding the plug against their skin first, letting them feel the temperature and anticipate what follows. I've found this builds psychological submission more effectively than rushing toward insertion.

Different submissives require different approaches—some need gradual coaxing, others respond to firm, decisive insertion. The key is reading their micro-expressions and adjusting my pace accordingly. Combined with restraint or sensory deprivation, this plug becomes an instrument of profound control. I use it to demonstrate absolute ownership over their most intimate sensations.
