Inflatable Radial Contact Dildo by Electrastim

Electrastim's Inflatable Radial Contact Dildo combines electrical stimulation with progressive expansion, letting you control both fullness and nerve-based sensation during solo or partnered play. Gold-plated electrodes deliver targeted pulses while you pump the shaft larger mid-session.

What it does

Gold-plated electrodes wrap around the shaft in a bi-polar system, sending electrical currents through radial contact points that spread across your entire vaginal or anal opening as you insert the deflated sex toy. Conductive gel applied to both the electrodes and your opening ensures the electrical pulses hit with consistent power, creating a tingling sensation that begins immediately.

Once the sex toy is inside, pump the inflation bulb gradually while increasing the intensity on your ElectraStim power unit. Each pump stretches your walls wider and spreads the electrode contact across more surface area, amplifying every electrical pulse. Your clit or prostate receives concentrated electrical contact while deep pressure builds through the expanding girth—combining nerve activation with physical stretching to drive arousal through dual pathways. Electro Chastity sex toys work differently, focusing on containment and denial rather than expansion and direct stimulation.

Fit and sizing

Starting deflated, this sex toy slides in easily for electro beginners—the manageable initial size means you can position the electrode ring just past your entrance before any expansion begins. As arousal builds and you pump the inflation bulb, the diameter expands gradually from 4 to 6.25 inches, accommodating different comfort levels and desired fullness. Progressive inflation lets you control the stretch rather than committing to one fixed size. Cockringshop specialise in products for men and couples, and we recommend choosing based on comfort and sensation preference rather than ego—start conservatively and increase inflation as your body responds to the dual electrical and physical stimulation.

How to use it

Connect both 2mm pin connectors to your ElectraStim power box before play begins. Apply conductive gel generously to the gold contacts and your opening, then insert the shaft slowly while completely deflated. Position the electrode ring just inside your entrance so it makes full contact with your inner walls and opening.

Once positioned, start your power unit on a low electrical pattern to feel the initial tingling. Pump the inflation bulb gradually while watching your body's response—increased muscle tension in your inner thighs and deeper breathing signal the dual sensation is working. Increase the electrical intensity on your power box as you continue inflating, letting the expanding pressure and growing electrode contact build your arousal. When you're done, deflate completely before removal and clean with toy cleaner.

Feature breakdown

Who it suits

This sex toy is built for people already comfortable with electro-play who want to add size variation to their sessions. If you enjoy the sensation of fullness and progressive stretching, the inflation feature will appeal to you—each pump intensifies both the physical pressure and the electrical contact working together. Anyone seeking nerve-based pleasure rather than friction alone will respond well to the electrical component.

Skip this sex toy if you don't have an ElectraStim power unit or aren't interested in electrical stimulation. While the deflated insertion size suits electro beginners, you need the power box to operate it, and the learning curve for combining inflation with electrical patterns may not suit everyone. If you prefer a fixed-size sex toy without the setup of dual controls, a standard electro-sex toy will be simpler.

How it compares

Standard electro-sex toys deliver electrical stimulation at a fixed size, while this inflatable sex toy lets you expand mid-session for progressive fullness. The expanding diameter means the electrode contact spreads across more surface area as you pump, amplifying sensation—something a rigid sex toy cannot do. Electro Cbt focuses on penile or testicular stimulation rather than internal vaginal or anal play, making it a different category altogether. Choose this sex toy if you want size control; choose a fixed-size electro sex toy if you prefer simplicity.

What you can use it with

Pair this sex toy with Couples Intimacy Kits that include complementary electro-sex toys, allowing both partners to experience electrical stimulation simultaneously during partnered sessions. The inflation feature works especially well when a partner controls the pump while you manage the power unit settings, creating a shared experience of building intensity and fullness together.
