Aluminium Electro-Stimulation Plug, Size XL 13 cm, 65 mm

65 mm of solid aluminium, with current on top

The Big John is a serious object: 65 mm in diameter and 580 g of metal. At this size, in a rigid material with zero give, you're in advanced-practice territory — and you don't get there without preparation.

The weight, the diameter, the conduction

The total rigidity of the metal doesn't forgive anything: unlike silicone, which compresses a little, aluminium holds its 65 mm exactly as they are. That's what makes this size demanding.

580 g of ballast. Once in place, the sense of weight is constant and makes up a good part of the experience.

Polished medical-grade aluminium is the best conductor in the catalog. The contact surface is huge, so the current spreads over a wide area instead of concentrating in one spot.

The contractions triggered by the current close down onto an already substantial diameter. It's an intense combination, one to approach with a good sense of your own tolerance.

The included pinch-proof cable connects to the Mystim control unit.

Preparation, equipment, and protocol

A long warm-up session, every time. Thirty minutes minimum with increasing sizes. At 65 mm in a rigid material, skipping this step causes injury.

The control unit isn't included. This plug is passive: without a Mystim electro-stimulation control unit (Pure Vibes or Tension Lover, sold separately), the e-stim function doesn't exist. Mystim items are only compatible with each other.

Water-based lubricant, in large amounts. Two reasons: comfort at this diameter, and conducting the current, which silicone and oil block.

Insert fully before connecting. Then bring it up from zero, very slowly.

Cut the power before removal.

Don't chase duration. At this size, a short, controlled session beats a long one that ends badly.

How to use it, without messing it up

Take your time on prep. The sphincter doesn't open on command. A hot shower, a few minutes to relax, one or two lubed fingers before moving to the plug: that's what separates an enjoyable session from one you cut short.

Lube, way more than you think. The anus produces no natural lubrication. Put some on the plug and at the entrance, and don't hesitate to place some inside too — an applicator does this very well. Reapply as soon as it starts to drag.

Go slowly, and in stages. Present the tip, let the body adjust, push gently, stop the moment it resists. Getting past the widest point is the critical moment: that's when you slow down, not speed up. Once past it, the plug settles into place on its own.

Breathe. Exhale as you push, it releases the sphincter. Holding your breath does exactly the opposite.

If it hurts, you stop. Discomfort, a stretch, some pressure: normal. Sharp pain, burning, blood: you pull out and let it rest. Pain isn't a stage to push through.

Removal happens slowly, never in one sharp pull, pushing gently as if going to the bathroom. If it resists, add more lube and wait.

A good position always helps. Squatting, lying on your side with one knee raised, or one foot on the edge of the tub. Standing bolt upright is the worst setup.

Reserved for advanced practice. At this diameter, the opening needs preparation: a warm-up session with a smaller plug, plenty of lube, and zero rushing. Forcing this size guarantees tearing.

The rules of anal safety

The flared base isn't a design detail. It's what stops the plug from riding up inside. The rectum literally pulls inward: an object without a base wide enough to stop it ends up in the ER. Never repurpose an object that wasn't designed for anal use, and never use a plug whose base is damaged.

Don't fall asleep wearing it. Prolonged wear compresses tissue and restricts local circulation. A few hours at most, and never a full night.

Clean before and after. Every time. Gut flora has no business anywhere else, and a poorly cleaned toy is a one-way ticket to a urinary or digestive infection.

One plug per person, or a condom. If you're sharing, put a condom on it and change it between each person. It's simpler and safer than a rushed cleaning job.

Change zones, change protection. Whatever went in the anus doesn't go in the mouth or anywhere else without being washed first.

If you get bleeding, pain that lingers, or a fever after a session, see a doctor. It's almost never serious if you don't let it slide.

Electro-stimulation: the rules that aren't up for debate

Nothing above the waist. This is the absolute rule of electro-stimulation. The current must never cross the chest cavity or come near the heart. No electrode on the torso, arms, neck, or head, and never two contact points on opposite sides of the trunk. All the play happens below the belt.

Firm contraindications. Pacemaker, implanted defibrillator, or any electronic implant: electro-stimulation is off the table, no exceptions. Also off-limits with heart rhythm disorders, heart disease, epilepsy, pregnancy, and in the presence of a metal implant in the area concerned. If you're unsure about your health, ask a doctor before buying.

Always connect after insertion and disconnect before removal. Never plug a cable into a powered-on control unit, and never pull out a plug while it's live.

Bring the intensity up from zero, every time. The threshold shifts from one day to the next, depending on hydration and fatigue. What felt comfortable yesterday can be too much today.

Water-based lubricant exclusively. Water conducts the current; silicone and oils insulate and create uneven contact points, which means unpleasant sensations or even localized tingling.

Never on broken skin or a damaged mucous membrane. A cut, irritation, a flare-up of hemorrhoids: wait until it's healed.

Never alone if you're new to this, and never under the influence of alcohol or anything that dulls perception. Your warning signal needs to be working.

Cut the power immediately if you feel sharp pain, burning, persistent numbness, or an abnormal tingling sensation after the session.

Cleaning and care

Compatible with every lubricant. Water-based, silicone, hybrid: metal doesn't react with any of them.

Cleaning: warm water and soap, or toy cleaner. Metal is non-porous and cleans without any trouble. Dry it thoroughly — leftover moisture eventually marks the finish and the rhinestone.

Watch out for the rhinestone. On jeweled models, avoid soaking it for long stretches: rhinestone glue doesn't like prolonged water contact. Quick clean, immediate drying.

Metal transmits temperature. It takes on room temperature, so it's cold on first contact. Warm it in your hands or under warm water before insertion, unless that's exactly the effect you're after.

Storage: in a padded pouch, away from objects that could scratch the finish.

FAQ — Your questions, our answers

Q: Can I get this if I'm comfortable with the John L?

A: There's a real gap between 50 and 65 mm, especially since metal doesn't give. Progress over several sessions with a long warm-up before attempting it.

Q: Why aluminium and not steel?

A: Polished medical-grade aluminium conducts the current very well while staying lighter than steel at the same volume. On a plug of this diameter, the weight difference is far from negligible.

Q: What lubricant should I use?

A: All of them, no restrictions — water-based, silicone, or hybrid. This material doesn't react with any of them. Use plenty, the anus doesn't lubricate itself.

Q: How long can I keep it in?

A: A few hours at most, and never while sleeping. Prolonged wear compresses tissue. Start with twenty to thirty minutes and extend it over sessions if you're comfortable.
