Catheters

Catheters are thin, flexible tubes inserted through the urethra to drain urine from the bladder. They're used medically for people with urinary retention, spinal injuries, or post-surgery recovery. In sexual contexts, some people use catheters for urethral play—the sensation of insertion and fullness in the urethra. This is an advanced practice requiring strict sterility to prevent infection.

Why Choose Catheters

1. Intense Urethral Sensation: The urethra contains sensitive nerve endings. Catheter insertion provides direct internal pressure and fullness that's significantly different from external stimulation. Insertion and withdrawal create distinct sensations.
2. Medical-Grade Safety: Catheters designed for sexual use are manufactured to medical standards, reducing infection risk compared to improvised alternatives. Proper materials prevent tissue damage during insertion.
3. Control and Precision: The tube's length and diameter are measured and consistent, allowing users to understand exactly what they're inserting. This predictability is essential for safe advanced play.

Types of Catheters

Silicone Catheters

Smooth, medical-grade silicone catheters are flexible and body-safe. They're easier to insert than rigid materials and conform to the urethra's natural curve. Silicone catheters can be boiled for sterilisation and last through repeated use. Available in various gauges for different experience levels. Check our full sex toy collection for catheter options.

Latex Catheters

Latex provides a firmer feel than silicone while remaining flexible. These catheters transmit sensation clearly and have a smooth, tapered insertion tip. Latex requires careful cleaning and storage away from heat. Some users prefer the tactile feedback latex provides during insertion and movement.

PVC Catheters

PVC catheters offer a middle ground between silicone's flexibility and latex's firmness. They're transparent, allowing visual feedback during use. PVC is typically less expensive than medical-grade silicone and remains popular for urethral play. Marked measurements on the tube help track insertion depth.

Open-Ended Catheters

These tubes remain open at the tip, allowing urine drainage or fluid passage. Open-ended designs are preferred by many for urethral play because they eliminate pressure buildup in the bladder. The drainage function also serves as a safety feature during extended wear.

Catheters Selection Guide

Who Buys Catheters

People with urethral sensation interest: Some individuals find the urethra more sensitive than external genitalia. Catheter insertion provides direct internal stimulation unavailable through other sex toys. The sensation of insertion, slow withdrawal, and the feeling of fullness create unique physical responses.

Advanced play enthusiasts: Experienced users exploring intense sensations often progress to urethral play. Catheters appeal to those seeking novel stimulation or specific BDSM dynamics. The practice requires knowledge of anatomy, sterilisation, and safety—attracting informed users rather than casual experimentation.

Choosing Catheters

• Gauge Size: Measured in French sizes (12-16mm typical). Smaller gauges suit beginners; larger gauges provide more intense sensation. Start smaller and progress only if experienced. Oversizing risks tissue damage.
• Material Durability: Medical-grade silicone withstands repeated boiling without degradation. Latex and PVC degrade faster. Consider how often you'll use the catheter and whether you want a reusable or single-use option.
• Insertion Tip Design: Smooth, tapered tips reduce insertion discomfort. Rounded rather than pointed tips are safer. Feel the tip before purchase if possible—sharp edges risk urethral tears.
• Length: Catheters range 20-40cm. Longer tubes allow deeper insertion; shorter tubes suit those preferring shallow placement. Know your anatomy and comfort level before selecting length.
• Sterilisation Compatibility: Check if the material allows boiling, autoclave sterilisation, or requires cold sterilisation solutions. Medical-grade silicone handles heat; some plastics warp. Proper sterilisation is non-negotiable for safety.

Looking After Your Catheters

Urethral play requires strict hygiene—infection risk is real and serious. Boil medical-grade silicone catheters for 10 minutes before first use and between sessions. Latex and PVC should be sterilised with cold sterilisation solutions designed for medical equipment. After use, flush the catheter with clean water immediately, then soak in a sterilising solution. Store in a clean, dry container. Never reuse a catheter that shows cracks, cloudiness, or material degradation. Use only water-based lubricant—oil-based products degrade materials and trap bacteria. Avoid silicone lube with latex catheters.

Urethral Lubricants

Urethral play requires specific lubricants designed for internal use. Water-based formulas are safest—they don't degrade materials or promote bacterial growth. Some users prefer thick, viscous lubes for slower sensation; others choose thinner formulas for easier insertion. Explore compatible products designed for advanced internal play.
