The essentials
Mystim Rocking Force S: what you need to know before you buy
Is it for you?
Who the Mystim Rocking Force S is for, and who it isn't for
It suits you if…
- You want to try anal e-stim and you have, or are going to buy, a Mystim powerbox.
- You're after a butt plug with a narrow, rounded tip that goes in easily.
- You're interested in prostate stimulation, because its shape is designed for that.
- You're starting out with anal toys and prefer a small size.
Better look elsewhere if…
- You don't have a powerbox and don't want to buy one. Without it, the butt plug gives no current.
- You'd rather have a butt plug that vibrates on its own, with nothing to connect.
- You already have experience and want more girth. The manufacturer has a wider L version.
Size and measurements
Mystim Rocking Force S size: a little longer than a bank card
It's 9.5 cm (3.7 in) long, a little more than a bank card and less than the height of a 33 cl can. It's 3.7 cm (1.5 in) in diameter, slightly less than a table tennis ball.
Measurements are from the manufacturer's website, which doesn't say how much goes in: with a butt plug, everything goes in except the base, which stays outside. It weighs 55 g, a little more than two AA batteries.

Step by step
How to use the Mystim Rocking Force S
- Wash it before use with warm water and mild soap, and dry it well.
- Apply water-based lubricant to the butt plug and to yourself. It's the kind that works with silicone.
- Connect it to the powerbox with the round Mystim connector, with the box switched off or at its minimum.
- Insert it slowly, tip first. The wide base always stays outside.
- Raise the intensity gradually from the powerbox, following its instructions.
Cleaning
Disconnect it from the powerbox and wash it with warm water and mild soap or a toy cleaner, without wetting the connection. Dry it well and store it away from other toys.
Our tips
- If you feel pain or stinging, stop and switch off the current.
- If you have a pacemaker or another electronic implant, or you're pregnant, talk to your doctor first.
- Don't move from anal to vaginal use without washing it first.
- If you use it with a latex condom, don't use oil-based lubricants or oils.
- Don't use it if the silicone is cut or damaged.

What the science says
What the science says about lubricant in anal sex
The studies we cite didn't test this butt plug. What has been studied is the use of lubricant in anal sex.
They used one of six water-based or silicone lubricants for 5 weeks. In anal sex, the water-based one was associated with more pleasure and satisfaction than using no lubricant. The study is about anal sex with a penis, not about butt plugs.

Questions
Mystim Rocking Force S: frequently asked questions
Does the Mystim Rocking Force S work on its own?
No. It needs a Mystim powerbox, such as Cluster Buster, Tension Lover or Pure Vibes, which connects with the round Mystim connector and is sold separately.
How big is the Mystim Rocking Force S?
9.5 cm (3.7 in) long and 3.7 cm (1.5 in) in diameter. It weighs 55 g.
Is the Mystim Rocking Force S good for beginners?
Yes. The manufacturer recommends size S for anyone with no anal experience: the tip is narrow and rounded and the silicone is soft. The current can come as a surprise, so start with the powerbox's lowest intensity.
Does the Mystim Rocking Force S have a base?
Yes. It has a wide base that stays outside and helps you control insertion.
Which lubricant works with the Mystim Rocking Force S?
A water-based one. The butt plug is silicone, and silicone lubricants can damage it.
How do I clean the Mystim Rocking Force S?
With warm water and mild soap or a toy cleaner, disconnected from the powerbox. The manufacturer doesn't publish its water resistance, so don't submerge it and keep water out of the connection.
