P-tainer Length Quiz
How it Works
Getting Started with Your P-tainer Kit
Step 1: Clean Everything
Clean your P-tainer and gripper using soap without moisturizers (Dawn Powerwash works well). Wash inner and outer surfaces, rinse thoroughly, and dry with a lint-free cloth. Make sure your fingers are dry too.
Step 2: Install the Gripper
Inspect the gripper and ensure the raised bumps and line are facing out. Position it over the small end of The P-tainer, tilt slightly, and use your thumb to roll it over the knob until fully installed. Flip the gripper up to prepare for putting it on.
Step 3: Prepare Your Skin
Ensure you are soft and your shaft skin is clean—excess skin oil can cause the gripper to slip. Pull back any foreskin to fully expose your glans.
Step 4: Check the Sizing
The P-tainer should cover about 50% of your glans. It's better to be slightly too small than too big. If unsure, learn how to measure.
Step 5: Position The P-tainer
Position The P-tainer with the V-shaped notch facing toward the ground. Carefully align the V shape with your frenulum and gently place it against your glans.
Step 6: Roll Your Skin Up
Roll your shaft skin up the body of The P-tainer as far as you can. You may need to gently grab your skin and pull it up to get it all the way to the neck of the retainer. If you can't reach the neck, your P-tainer may be too long.
Step 1: Flip the Gripper Down
While holding your skin with one hand, use your other hand to carefully flip the gripper over the rolled-up skin.
Tip: Group your thumb, pointer, middle, and index finger together, placing them evenly around the gripper while it's flipped up. Hold your skin in place with your other hand, then press the edge of the gripper down evenly until it flips over the skin.
Step 2: Adjust Your Skin (Critical for Comfort & Grip)
Adjusting your skin under the gripper is critical to comfort and optimal grip:
- Gently pinch the gripper from the side while carefully pulling any extra or bunched-up skin down to the line around the gripper
- Work your way around the entire gripper until all skin is aligned with the raised line
- Double-check that no skin appears bunched up
- Give The P-tainer a tug to confirm a secure grip
- If you pulled too much skin out, flip the gripper back up and start again
Stiff vs Soft Grippers
- Stiff Grippers (fully clear, not opaque) – Recommended for the highest grip available. Great for adding tension with weights or straps.
- Soft Grippers (opaque/cloudy) – Recommended for just retaining without tension. Maximum comfort for all-day wear.
Comfort Fit vs Snug Fit
- Comfort Fit: Same size as your P-tainer – gentler grip, great for beginners or longer sessions
- Snug Fit: One size smaller than your P-tainer – tighter grip for increased hold
Count the dots around the top of the gripper to determine size. Start with the same number as your P-tainer size.

Step 1: Screw In the Bulge
Simply screw the Retainer Bulge into the threaded end of The P-tainer. Hand-tighten only—don't overtighten.
Step 2: Why Use a Bulge?
- Creates a natural shape under clothing
- Reduces pee dribbling after using the restroom
- Adds a small amount of weight for passive tension
Ready to Add More Tension?
Your P-tainer is compatible with all Stealth Retainer accessories. When you're ready to progress:
Daily Wear
- For best results, wear 8-12 hours daily
- Take a break every 2-4 hours
- Check circulation regularly
- Reposition the gripper if needed (flip it back up and adjust your skin)
Underwear & Pants
- Most underwear styles work for just retaining
- Boxer briefs provide good support
- The retainer bulge creates a natural look under clothes
Activity Level
- Safe for most daily activities
- For swimming or running, remove accessories and use retainer only
- Sweaty? A snug fit gripper helps reduce slippage
- Take breaks – Remove the device every 2-4 hours to check circulation
- Stop if uncomfortable – Numbness, pain, or discoloration means remove immediately
- Keep it clean – Wash your device and skin before each session
- Start slow – Let your body adjust to wearing the retainer before adding tension
