Step-by-Step Guide: How to Use the Kastuni Masturbation Cup

Using the Kastuni cup is simple, but following the correct steps can maximize both pleasure and safety.

Step 1: Prepare the Cup

Before first-time use or after each cleaning:

• Unscrew and disassemble the cup if it comes in multiple parts.

• Remove the inner sleeve from the shell.

• Wash the inner sleeve with warm water and mild, unscented soap or a specialized sex toy cleaner.

• Rinse thoroughly and allow it to air dry completely before reassembling.

💡 Tip: A clean cup ensures better hygiene, longer lifespan, and avoids unwanted odors or bacterial growth.

Step 2: Apply Water-Based Lubricant Generously

• Add a generous amount of water-based lubricant inside the sleeve entrance.

• Also apply some lube to your penis.

• Avoid silicone or oil-based lubes, as they can damage the TPE/silicone sleeve over time.

Lubrication is essential for comfort, realism, and to prevent tearing of the sleeve or irritation to your skin.

Step 3: Insert and Start Slowly

• Insert your penis gently into the cup.

• Start with slow, shallow thrusting movements to allow your body to adjust and build stimulation.

• Use your hand to grip the outer shell — some users prefer rotating, twisting, or pumping motions for added pleasure.

If your model includes an air release or suction control valve, you can experiment by covering or uncovering the vent to adjust internal pressure.

Step 4: Experiment With Angles and Rhythm

Each internal texture in the Kastuni sleeve is designed to stimulate different parts of the penis. To fully enjoy the range of sensations:

• Try varying your thrust speed, angle, and depth.

• Use both hands or even a thigh hold or pillow wedge for hands-free action.

• Edge yourself by pausing right before climax, then slowing down again.

You can even incorporate erotic videos, fantasy scenarios, or VR porn for immersive stimulation.

Step 5: Reach Climax and Clean Up Properly

When you’re ready to finish:

• You can climax inside the sleeve, as it’s designed to hold fluids.

• Carefully remove the cup from your body.

• Disassemble and immediately clean the sleeve and cup thoroughly.

⚠️ Do not delay cleaning, as semen can breed bacteria and lead to unpleasant odors.

Cleaning & Maintenance: Essential for Longevity and Safety

Proper care of your Kastuni masturbation cup will keep it hygienic and extend its lifespan.

Cleaning Steps:

1. Rinse the sleeve with warm water immediately after use.

2. Use mild soap or toy cleaner (never harsh cleaners).

3. Rinse again until no soap remains.

4. Pat dry with a soft cloth and leave to air dry in a ventilated place.

5. Once dry, sprinkle cornstarch (not talcum powder) to restore softness and prevent stickiness.

6. Store it in a cool, dry place, ideally in its original case or a clean storage bag.

Common Mistakes to Avoid

• Using oil- or silicone-based lubricants – These degrade the sleeve material.

• Skipping cleaning – Can cause bacterial infections or toy damage.

• Drying with heat (e.g., hair dryer) – Heat can warp or melt soft materials.

• Storing it wet or sealed – Leads to mold and odor.

Advanced Tips for Enhanced Pleasure

1. Warm It Up First

• Soak the inner sleeve in warm water for 5 minutes before use.

• This gives it a more lifelike, body-temperature sensation.

2. Combine with a Cock Ring

• Using a cock ring alongside the cup can enhance erection strength and make orgasms more intense.

3. Try Edging or Stamina Training

• Masturbate to the edge of orgasm, then stop.

• Repeat 3–4 times before climax.

• This technique can train you to last longer during real sex.

4. Use in the Shower (if waterproof)

• Some users enjoy using it in warm water settings for added relaxation and easier cleanup.

• Make sure your model is waterproof before trying this.

Is the Kastuni Masturbation Cup Safe?

Yes, when used correctly and kept clean. Most Kastuni cups are made from body-safe TPE or silicone. Still, it’s important to:

• Avoid sharing with others.

• Clean thoroughly between uses.

• Watch for signs of irritation or allergy.

• Replace the sleeve if it becomes sticky, torn, or degraded.

Who Can Use It?

The Kastuni masturbation cup is suitable for:

• Men exploring solo pleasure.

• Individuals with erectile concerns wanting performance training.

• People seeking discreet, safe sexual outlets.

• Anyone needing a break from hand-only masturbation.

It’s a helpful tool for both pleasure and sexual wellness.
