The Tunnel Penis Plug delivers intense sensations through medical-grade stainless steel construction and a hollow core that maintains functionality during wear. Its tapered profile and integrated glans ring ensure safe positioning while providing the advanced urethral stimulation that experienced practitioners seek.
Once inserted, this plug creates a constant awareness of fullness that radiates through your entire shaft. The hollow center allows natural functions to continue uninterrupted, while the steel walls conduct temperature and pressure in ways that amplify every sensation. The tapered design means you feel the stretch gradually increase as it settles into position, creating layers of intensity that shift with every movement.
During arousal, the metal conducts heat from your body while the varying width creates different pressure points along your urethra. The glans ring adds external stimulation, creating a dual sensation that combines internal fullness with surface pressure. When orgasm approaches, the hollow design allows release while the plug remains in place, creating a completely different ejaculatory experience.
Proper preparation is essential - sterilize the plug and use plenty of sterile lubricant specifically designed for urethral play. Insert slowly, allowing your body to adjust to each width increment as you progress. The glans ring should rest comfortably against the head of your penis, indicating proper depth. Never force insertion or ignore discomfort.
Once positioned, you can engage in normal activities or incorporate it into play sessions. The hollow design means you don't need to remove it for urination, though thorough cleaning afterward is essential. For extended wear, monitor comfort levels and remove if any pain or unusual sensations develop. Always prioritize safety over sensation intensity.
This plug is exclusively for experienced practitioners who understand urethral anatomy and safety protocols. If you're new to sounding, start with smaller, simpler designs before considering this advanced option. The substantial girth and length make it unsuitable for beginners or those with any urethral sensitivities or medical conditions affecting the urinary tract.
Ideal users are confident in their technique, understand sterile practices, and have experience with graduated sizing. The hollow design appeals to those who enjoy extended wear scenarios or want to incorporate urethral play into longer sessions without interruption for natural functions.

While not a traditional chastity device, The Tunnel Penis Plug shares the control and restriction elements that define this category. It creates a form of mental and physical restraint through its presence, making the wearer constantly aware of their state while maintaining functionality. The psychological impact mirrors chastity play dynamics.
This plug functions as an internal chastity component, creating sensation without preventing function. Unlike cages that restrict access, this device provides internal control while allowing external freedom. It represents an advanced form of intimate control that experienced users incorporate into power exchange scenarios.

The Tunnel Penis Plug demands respect - this isn't something you use casually. At 12mm maximum width, the stretch is significant and requires patience during insertion. Once seated properly, the sensation is unlike anything else I've experienced. The hollow design means I could wear it for over an hour without needing removal, which completely changes how you approach urethral play. The temperature of the steel shifts with arousal, creating this incredible contrast between the cool metal and heated tissues. When I finally came with it in place, the experience was intensely different - not better or worse, just completely unique. The glans ring adds just enough external pressure to remind you it's there even when you're not actively focusing on the internal sensations. This is definitely advanced territory.
