Penis Enlargement System by Size Doctor

Many men worry their penis size affects confidence and sexual satisfaction. The Size Doctor Penis Enlargement System uses mechanical traction technology to stimulate natural cellular growth, delivering measurable length and girth gains through consistent, controlled pressure over time.

What it is

The Size Doctor Penis Enlargement System is a professional-grade extender that applies consistent mechanical traction to stimulate natural cellular growth in penile tissue. Built from medical-grade ABS, silicone, and aluminum, it combines durability with comfort for long-term wear. The system works by applying gentle, sustained pressure that encourages cellular multiplication—a scientifically-backed approach to enlargement that targets both length and girth without chemicals or temporary fixes.

What sets this system apart is its modular design: multiple interchangeable extension bars (0.5cm, 2cm, and 4cm) let you customize pressure and length gains to your body. Adjustable girth-fixing bands ensure a secure, comfortable fit during wear. See the full BDSM Australia range of Penis Sleeves to explore complementary products for your enhancement journey.

How to use a pumps, extenders and sleeve

Start by reading the instruction manual carefully to understand each component. Select the appropriate extension bar based on your desired length, then attach it securely to the extender body. Fit the girth-fixing bands snugly around your penis to hold the device in place. Begin with short wearing sessions—15 to 30 minutes—and gradually increase duration as your body adapts. Ensure consistent, gentle pressure throughout wear; the goal is steady, long-term growth, not discomfort.

Wear the system regularly for best results, tracking your progress with periodic measurements. Some users combine extender sessions with manual exercises for enhanced outcomes. Clean all components thoroughly with mild soap and warm water after each use, then air-dry completely before storage. Explore Vibrating Penis Sleeves to complement your enlargement routine with additional sensations during wear or recovery periods.

Care and storage

Clean the extender body, bars, and bands with mild, unscented soap and warm water after each use. Dry all components thoroughly with a soft cloth and allow them to air-dry completely before reassembling. Store the system in its provided gift box in a cool, dry place away from direct sunlight and extreme temperatures. Check components regularly for signs of wear or damage, and replace any worn bands or parts to maintain safety and effectiveness.

Mistress Athena's training notes

By Mistress Athena — professional dominant and kink educator, sole instructor behind BDSM Australia's library of training videos. Read her full bio →

The Size Doctor system fascinates me as an instrument of psychological transformation. Watching a submissive submit to the discipline of consistent wear—the daily ritual, the gradual progress, the physical evidence of change—creates layers of control that extend far beyond the device itself. My subjects internalize their growth as proof of my authority over their most intimate self.

Each adjustment of the extension bars becomes a moment of deliberate dominance. I dictate progression, timing, and intensity. Some of my submissives report heightened sensitivity during wear; others describe a meditative surrender to the mechanical pressure. This dual effect—physical transformation paired with psychological surrender—makes the system invaluable in my practice.

What impresses me most is how this device operates silently, invisibly, between sessions. My submissives carry my control with them throughout their day. The knowledge that they're wearing it, that their body is changing under my instruction, creates a constant thread of submission. Documentation becomes part of the ritual: measurements, photographs, progress reports all feed back into my control structure.
