Diameter Urethra Probe by Electrastim

The Diameter Urethra Probe by Electrastim is a medical-grade stainless steel urethral probe that delivers electrical stimulation through the urethra. It combines precise insertion with controlled electro-stimulation to create pulsing sensations. It suits men experienced with urethral play who want to explore electro-play in a highly sensitive area.

About this product

The Diameter Urethra Probe by Electrastim is a specialised urethral stimulator built from medical-grade stainless steel to conduct electrical current safely and consistently. The tapered design guides insertion while the seamless surface minimises irritation. Unlike standard penis plugs, this probe is engineered specifically to work with an Electrastim power unit, creating electrical sensations that travel directly through your most sensitive tissue.

The steel construction ensures perfect electrical conduction while maintaining the hygiene standards required for urethral play. Each probe is made to precise tolerances, so the taper remains consistent and insertion stays smooth and controlled. What makes this different from basic urethral toys is the electrical component—the current creates waves of sensation that build from inside, something mechanical insertion alone cannot replicate.

Features worth knowing

• Medical-grade steel: Body-safe material that conducts electricity perfectly whilst remaining hygienic and straightforward to clean between uses.
• Tapered insertion: Sleek shape guides comfortable entry and positions the tip for precise electrical stimulation exactly where needed.
• Variable intensity control: Adjust the electrical current via your Electrastim power unit to build sensations from gentle tingles to intense pulsing waves.
• Seamless construction: Smooth surface prevents snagging and ensures safe insertion and removal every time without catching or irritation.
• Electrical conduction: The steel conducts current directly into urethral tissue, creating sensations impossible to achieve with non-conductive probes.

How to use a penis plug safely

Before insertion, wash the probe thoroughly with warm water and mild soap, then sterilise it by boiling for three minutes or using a sterilisation method suitable for medical-grade steel. Allow it to cool completely. Empty your bladder, then wash your penis and urethra with warm water. Apply a generous amount of sterile lubricant specifically designed for urethral play—this is essential, as the urethra produces minimal natural lubrication. Insert the probe slowly and gently, allowing the tapered shape to guide it. Never force insertion or push beyond mild resistance.

Once inserted, connect the probe to your Electrastim power unit using the appropriate connector. Start with the lowest intensity setting and allow yourself to adjust to the sensation before increasing power. Sessions should be kept relatively short initially—ten to fifteen minutes is a sensible starting point. Remove the probe gently after your session, disconnect it from the power unit, and clean it immediately with warm water. After use, inspect the probe for any damage before storage. Many people exploring Sperm Stoppers find that combining urethral play with other forms of stimulation requires extra attention to hygiene and comfort.

Care and storage

Clean the probe with warm water and mild soap immediately after use, then dry it thoroughly. Before first use and between partners, sterilise it by boiling for three minutes or using medical-grade sterilisation methods suitable for stainless steel. Store it in a clean, dry place away from other materials that might scratch the surface. Do not use harsh chemicals or abrasive cloths that could damage the steel or create microscopic scratches where bacteria might harbour.

This knowledge ensures you get the most from your probe whilst maintaining complete safety.

What to expect

First-time users often underestimate how intense electrical urethral stimulation feels compared to mechanical insertion alone. Even at low intensity settings, the sensation is distinctive—a pulsing, building awareness that travels through tissue electrical stimulation reaches in ways mechanical probes cannot. Many people find the first session surprisingly intense and benefit from keeping it short, around ten minutes, to allow their body to adjust.

Insertion itself tends to be smoother than beginners expect, provided you use adequate sterile lubricant and insert slowly. The tapered design guides entry without requiring force. The real learning curve is managing electrical intensity—starting low and increasing gradually prevents overwhelming sensation. Your comfort and response will guide you faster than rushing intensity upward.

Cleaning and sterilisation are straightforward with stainless steel, though urethral play demands more rigorous hygiene than many other products. The probe requires boiling or proper sterilisation before first use and between different partners. Most users find this becomes routine once they establish a clear protocol.

Long-term, this probe holds up excellently if treated carefully. Stainless steel does not degrade from electrical use, and the seamless construction avoids the weak points where other materials fail. Users who respect the intensity this product delivers and maintain proper hygiene report years of reliable use.
