Tunnel plugs are hollow anal toys designed for penetration and stimulation while allowing fluid passage. The hollow core lets users experience fullness while maintaining urethral access, making them popular for specific sensations during solo play or partnered sex. The toy inserts into the anus, and internal nerve endings respond to pressure and the sensation of the hollow passage.

Why Choose Tunnel Plugs

  1. Hollow Core Design: The tunnel allows complete fluid passage while the plug remains inserted. This is practical for extended wear and eliminates the need to remove the toy for urination, which appeals to users seeking long-term wear comfort.
  2. Dual Sensation: The hollow passage creates internal sensation distinct from solid plugs. Users experience fullness from the plug walls combined with the unique feeling of the hollow core, offering a different type of anal stimulation.
  3. Material Stability: Stainless steel and glass tunnel plugs hold their shape under pressure and conduct temperature well. Silicone versions offer flexibility and are easier to insert for beginners exploring anal play.

Types of Tunnel Plugs

Silicone Tunnel Plugs

Silicone tunnel plugs offer flexibility and grip without rigidity. The material stretches slightly during insertion, making entry easier for beginners. Silicone warms to body temperature and provides a softer sensation against anal walls. These plugs come in various colours and often feature tapered tips for comfortable insertion. You can explore our full range of sex toys including anal options.

Stainless Steel Tunnel Plugs

Steel tunnel plugs are rigid and durable, maintaining their shape under pressure. They're heavier than silicone, creating stronger fullness sensations. Steel responds well to temperature play—chill in water or warm under running water before insertion. The smooth surface slides in easily and cleans without absorption risk, making steel ideal for extended wear sessions.

Borosilicate Glass Tunnel Plugs

Glass tunnel plugs are non-porous and temperature-responsive like steel but lighter in weight. They're completely transparent, offering visual appeal during solo play. Glass is inherently smooth and won't degrade over time. These plugs work well with any lubricant and are easy to clean. Some users appreciate the psychological aspect of visibility during extended wear.

Graduated Tunnel Plugs

Graduated designs feature a tapered shaft that increases in width toward the base. The gradual widening allows progressive stretching and insertion without sudden size jumps. These plugs suit users building anal capacity or those wanting controllable depth insertion. The gradual taper makes them less intimidating for beginners while still providing substantial fullness at full insertion.

Tunnel Plugs Selection Guide

Type What It Does Key Feature Size/Spec
Silicone Tunnel Provides flexible anal fullness with easy insertion Stretches slightly, body-warming 25–50mm diameter
Steel Tunnel Creates intense fullness with rigid pressure Temperature-responsive, heavy 30–45mm diameter
Glass Tunnel Smooth insertion with temperature control Non-porous, visual clarity 28–50mm diameter
Graduated Tunnel Progressive stretching from tip to base Tapered shaft, capacity building 20–50mm taper range
Large Capacity Tunnel Maximum fullness sensation with hollow core Wide diameter, experienced users 50–60mm diameter

Who Buys Tunnel Plugs

Experienced anal play users: Men and women already familiar with anal toys seek tunnel plugs for novel sensations. The hollow core offers distinct pressure and passage feedback compared to solid plugs. Extended wear becomes practical since the tunnel design eliminates obstruction, allowing longer sessions without discomfort.

Users exploring urethral access: Some people want anal fullness while maintaining urethral sensation. Tunnel plugs accommodate this by allowing complete passage through the hollow centre. This appeals to those with specific anatomical interests who want simultaneous anal and urethral involvement.

Choosing Tunnel Plugs

  • Starting Size: Begin with smaller diameters (25–30mm) even if experienced with anal play. The hollow core creates unique sensations that may feel larger than equivalent solid plugs. Size up gradually once you're comfortable.
  • Insertion Difficulty: Tapered tunnel plugs ease insertion more than cylindrical ones. Graduated designs provide progressive width, reducing the stretch required at full insertion. This matters for comfortable wear duration.
  • Material Durability: Stainless steel and glass never degrade or absorb bacteria. Silicone can develop surface damage over time. Choose your primary material based on how frequently you'll use the toy and how you clean it.
  • Weight and Sensation: Heavy materials (steel) intensify fullness through gravitational pressure. Lightweight options (glass, soft silicone) provide subtle sensations. Consider what physical feedback you actually want during extended wear.
  • Base Design: A flared, wide base prevents insertion fully into the anus and makes removal simple. Avoid plugs with narrow bases. The base should be substantially wider than the widest part of the shaft.

Looking After Your Tunnel Plugs

Wash tunnel plugs with warm water and mild soap immediately after use, paying attention to the hollow passage—use a small brush or cloth to reach inside. Silicone toys pair with water-based lube only, as silicone-based lubes degrade silicone material. Steel and glass work with any lube type. Dry completely before storage to prevent bacterial growth in the hollow core. Store in a clean, dry container away from other toys to prevent silicone staining. Boil glass or steel plugs for 10 minutes monthly if desired for thorough sanitisation.

Goes Well With

Vibrators for Blended Stimulation

While a tunnel plug provides internal anal sensation, a vibrator on the external genitals creates blended pleasure. Many people climax more easily with simultaneous anal fullness and clitoral or penile vibration. Vibrators in various styles pair naturally with static anal plugs during masturbation or partnered sex.

Frequently Asked Questions

What are tunnel plugs?
Tunnel plugs are hollow anal toys designed for penetration while maintaining fluid passage through their core. The internal walls create fullness sensations while the open centre allows urethral access during extended wear.
How do tunnel plugs create sensation during use?
Pressure from the plug walls stimulates anal nerve endings while the hollow passage produces distinct internal sensations separate from solid plugs. Users experience combined fullness and the unique feeling of the hollow core simultaneously.
Can tunnel plugs be worn for extended periods?
Tunnel plugs accommodate extended wear because the hollow core permits fluid passage without requiring removal for urination. Stainless steel and glass versions maintain consistent shape under prolonged pressure, supporting comfortable long-term insertion.
Who benefits most from tunnel plugs?
Men exploring dual sensations during solo play gain from the hollow core design. Couples seeking hands-free anal stimulation during sex find tunnel plugs practical because fluid passage eliminates interruption.
