The Shaft Model P Cock & Ball Stretcher is crafted from 100% FLEXISKIN™ liquid silicone — a flexible, body-safe material that delivers a smooth, snug fit without harsh rigidity. Designed to stretch both the penis and scrotum simultaneously, it works by gently constricting blood flow to keep blood retained in the shaft, which can heighten sensitivity, delay climax, and support firmer, longer-lasting erections. The device sits at a total height of 3.1 inches, with a ball stretcher diameter of 1 inch, an entry hole diameter of 1.2 inches, and a shaft diameter of 1.5 inches — proportions that suit a wide range of bodies while keeping tension comfortable and controlled. Its all-silicone construction means it warms naturally to body temperature and moves with you throughout a session.

Intensity & Experience Level
Level: Beginner | Sensation: Restrictive / pressure
The soft FLEXISKIN™ construction makes this one of the more forgiving entries into cock and ball play — it stretches easily and sits gently rather than biting into skin. First-timers will find it approachable, while intermediate users can layer it into edging and orgasm-control routines to push intensity further over time.
Who is this product for?
- Sensation seekers exploring edging: Those who want to amplify arousal and delay climax through gentle restriction
- Beginners to cock and ball toys: Anyone wanting to start with a soft, body-safe material before progressing to firmer devices
- People experiencing erectile challenges: Individuals who want to experiment with blood-flow retention to support firmer erections — note this is exploratory, not a medical solution
- Partnered players: Couples looking to add visual intensity and new tactile dimensions to shared intimacy
- Edging and orgasm-control enthusiasts: Those who pair restriction devices with sleeves or vibrators for heightened orgasm control
How to use the Shaft Model P Cock & Ball Stretcher?
- Warm the toy: Hold it under warm running water for 30–60 seconds to soften the silicone for easier stretching and a more comfortable fit.
- Trim pubic hair: Reduces the chance of pulling or pinching during application or removal.
- Lubricate generously: Apply water-based lube to both the toy and your genitals to reduce friction throughout the process.
- Insert one testicle at a time: Gently stretch the toy with your hands and slide one testicle through the entry hole, then the other, followed by the penis shaft.
- Adjust for fit: Settle the toy into a snug, comfortable position — it should sit firmly without pinching, rolling, or causing sharp discomfort.
- Comfort checkpoint: Once on, check for numbness, pain, or colour change. If any of these occur, remove the toy immediately. For first-time use, limit sessions to 15–20 minutes and increase duration gradually as your body adjusts.
- Remove carefully: Apply additional lube to the base of the scrotum, stretch the toy gently, and slide it off in reverse order — penis first, then each testicle.
Techniques & ways to play
- Solo edging: Wear the stretcher during masturbation and pair it with a stroker sleeve to prolong arousal and intensify the eventual orgasm through sustained tension.
- Solo vibration pairing: Combine with a vibrator against the perineum or shaft for layered sensation while the stretcher maintains restriction.
- Standing doggy-style (partnered): Allows your partner to experience the texture and visual appeal while you feel the restricted tension during penetration.
- Face-to-face missionary (partnered): Keeps both partners in sync and heightens connection while the added intensity of the stretcher is felt throughout.
- Spooning (partnered): Leisurely, intimate strokes ideal for adjusting to new sensations at a relaxed pace.
- Dom/sub dynamics: The dominant partner can oversee application and monitor the wearer's comfort, setting agreed time limits before the scene begins — always establish a safe word and check in regularly before escalating duration or intensity.
Pairs well with / Complete the scene
- Water-based lubricant: Essential for application, comfort during wear, and safe removal — required with this toy
- Stroker sleeves: Combine with a textured sleeve for edging play and prolonged arousal sessions
- Vibrators or wand massagers: Apply to the perineum or shaft while wearing the stretcher for layered stimulation
- Cock rings: Layer with a separate cock ring for additional shaft restriction and visual impact
- Restraints or sensory deprivation: Pair with blindfolds or cuffs to deepen the power-exchange experience
How to clean and care
Cleaning: Wash thoroughly with warm water and a mild, unscented soap or a dedicated silicone-safe toy cleaner after every use. Rinse completely to remove all soap residue.
Drying: Pat dry with a clean, lint-free towel and allow to air dry fully before storing.
Lubricant compatibility: Use water-based lubricant only. Silicone-based lubricants can degrade FLEXISKIN™ silicone and compromise the material over time.
Storage: Store in a cool, dry place away from direct sunlight. Keep away from other silicone toys — silicone-on-silicone contact can cause surface breakdown. A dedicated pouch or separate compartment is ideal.
Additional information
The Shaft Model P is suitable for both solo and partnered external use. Its silicone construction is durable and long-lasting when cared for correctly. The constriction mechanism may be of interest to those who experience difficulty maintaining an erection or who deal with premature ejaculation, as it works by retaining blood flow within the shaft — this can support firmer erections for longer and delay orgasm. Erectile dysfunction and premature ejaculation have many contributing factors, and a cock and ball stretcher will not resolve all cases, but it may provide meaningful support and is worth exploring.
Note that some hand strength is required to stretch the toy wide enough for application and removal. Users will also need comfortable reach to access their genitals during fitting. Those with limited hand mobility or restricted range of motion may find this product more challenging to use independently.
Special considerations / warnings
- Hand strength required: Stretching FLEXISKIN™ silicone wide enough for fitting requires a degree of grip and hand strength — factor this in before purchase if you have limited dexterity.
- Reach required: Users need adequate range of motion to access and adjust the toy on the genitals.
- Time limits: Do not wear for extended periods, especially during first use. Begin with 15–20 minutes and increase gradually. Never sleep while wearing a cock and ball stretcher.
- Stop immediately if: You experience numbness, sharp pain, a cold or blue discolouration of the skin, or any loss of sensation. Remove the toy at once and allow circulation to normalise.
- Pubic hair: Trim or shave the area before use to reduce the risk of hair being caught during application or removal.
- Medical flag: If you have a diagnosed circulatory condition, blood clotting disorder, diabetes, or any condition affecting genital blood flow or nerve sensitivity, consult a healthcare professional before using any constriction device.
- Not a medical device: This product is not intended to diagnose, treat, or cure any medical condition, including erectile dysfunction or premature ejaculation.
