ElectraStim Nona silicone G-spot stimulation electrode

Nona is an internal stimulation electrode designed for deep massage sensations. Its pronounced upward curve and bulbous tip naturally follow the anatomical contours of the G-spot or prostate. The textured ridges intensify every pulse from the stimulator, creating a massage effect that I consider one of the most effective in internal electrical stimulation.

The silicone used here is medical-grade, 100% platinum-cured — a guarantee of biocompatibility and durability. The anchored base keeps the electrode stable during stimulation, while the tapered shaft facilitates insertion. To me, this is a design that won the Best Product Design award at the 2015 Calvista AdultEX Awards, and it shows.

Medical-grade silicone material and care

Platinum-cured silicone is non-porous, hypoallergenic, and extremely durable. Unlike elastomer materials, it does not retain bacteria and can be easily cleaned with warm, soapy water after each use. I recommend a gentle cleaner or a specialized sex toy disinfectant between regular uses. No silicone-based lubricant (incompatible) — use only water-based or oil-based lubricant (a compatibility test on a small area is recommended first).

Dimensions and internal size

Nona measures 90 mm of insertable length (3.5 inches) with a maximum circumference of 110 mm (4.3 inches). This size places it in the intermediate-to-advanced range — not too thin for experienced users, yet not too substantial for beginners. Its 122 g weight gives it a noticeable tactile presence. For beginners in internal electrical stimulation, I recommend starting with gentle exploration at the stimulator’s lowest settings, then gradually increasing the intensity.

Compatibility and operation

Nona is bipolar (2 connectors with 2 mm pins) and works ONLY with a compatible ElectraStim stimulator. The electrode itself does not vibrate or buzz — it delivers electrical pulses controlled by the device to which you connect it. This is a BDSM/electrical stimulation accessory, not a standalone sex toy. You must own an ElectraStim stimulator (Sensatouch, Flick Stimulator, etc.) to experience the sensations described. I find this modular approach very smart: you can combine multiple electrodes with a single stimulator according to your preferences.

Use and safety

Before first use, clean the electrode with warm, soapy water. Apply plenty of water-based lubricant before insertion. Start at a very low intensity on the stimulator and increase gradually. Internal electrical stimulation requires clear consent and ongoing communication with your partner. If sharing, use an external condom for safety. After each use, clean, dry completely, and store in a cool, dry place. To learn more about practicing BDSM safely, I recommend consulting our complete guide to BDSM domination.

Who it is designed for

Ideal for: Couples or solo users experienced in electrical stimulation, women seeking intense and precise G-spot stimulation, men interested in prostate stimulation, and people looking for controlled, adjustable electrical BDSM sensations.

Not for: Complete beginners in electrical stimulation (start with simpler electrodes or introductory guides). People with a pacemaker, electronic implant, or medical contraindications to electrical stimulation. If you are new to electrical BDSM, I recommend exploring our introductory BDSM accessories first to better understand your preferences.

A friend’s advice — Internal electrical stimulation is a rewarding practice, but it requires respect for the body and good communication. Nona is an excellent tool if you already understand the basics. Otherwise, take the time to learn first.
