Green areas represent lower intensity. Red areas represent higher intensity.

How does the sleeve heatmap work?

TechySex uses custom software to analyze inner sleeve texture, diameter variation and some other parameters to identify hotspots within the sleeve.

This data is represented as a heatmap, highlighting the expected intensity and the level of stimulation.

Areas that are more intense are highlighted in red, and areas that are less intense are mapped in green.

Depending on your personal preference, you may opt for either a light sleeve with smooth textures or a more intense counterpart with high diameter variability and rougher textures.

What's good

  • Compact and unique design
  • Good bang for the buck
  • Easy to clean and dry, flips inside out
  • Squeezable, intensity can be controlled
  • Spinning motion if you cover the vacuum hole

What's not so good

  • Limited insertion length
  • Storage is a bit annoying
  • Feels a bit cheap

Tenga Flex: Fizzy Green Review

I recently got to try one of the new products released by Tenga. This time, it’s Tenga Flex, a figure-eight-shaped masturbator which, despite its relatively small size, is packed with features. 

This includes the ability to create the vacuum (suction for days!), the spinning effect, and also a squeezable exterior for more intense sessions.

Join me in this deep dive to see what you can expect if you do decide to get one.

*Tenga sent us a Flex Fizzy Green in exchange for an honest review. This does not impact our judgment.

What you get with Tenga Flex

Nowadays some sex toys come in very well-thought-out, high-end packaging. The materials sometimes feel so premium can almost seem like you’re unboxing the latest iPhone.

Well, don’t expect this with Tenga Flex because it comes in an inexpensive see-through plastic cover. It’s sealed, so you know it hasn’t been opened but that’s pretty much it when it comes to unboxing. I wouldn’t say it’s bad though, as this allows Tenga to cut some costs and offer you a product that’s a bit more affordable.

Anyway, when you buy this toy, you’ll get:

  • The masturbator itself
  • One sample of Tenga Hole lube
  • User manual

The masturbator includes the sleeve, the outer case, and a special stick that you use to push the sleeve into the case (normally it’s not that easy to do because of the way the toy is shaped). The stick is also used as a support when drying the sleeve.


At the time of writing, there are currently 4 different Tenga Flex masturbators. They’re all very similar and they only differ in exterior color and sleeve texture.

The Tenga Flex Fizzy Green is one of the two which are narrower and presumably more intense. It has several different chambers that vary in diameter and texture.

Fizzy Green’s texture is composed of very small rhomboid shapes which sort of remind me of Tenga Spinner Pixel. Just like with the Spinner, the shapes are arranged in a spiral, which assists the twisting effect (more on that later).

Vacuum and Suction

The toy has a hole at the top that you can plug with your finger. Doing this causes the air around the sleeve to escape as you push in. This creates a vacuum, causing a strong suction effect as you stroke the toy.

Just note that the sleeve itself is closed (there’s no opening at the end), meaning the vacuum is created around the sleeve and not inside of it. The vacuum within the sleeve occurs naturally as you insert, but this vacuum will vary depending on how deep you insert your penis (the deeper you go, the more air will be pushed out).

Spinning Effect

Thanks to a twisty exterior, the Tenga Flex tends to, um, flex when there is a vacuum inside. This is quite neat and it causes the toy to spin slightly on each stroke.

The effect is not as pronounced as with Tenga’s Spinner, but it’s still a great feature that I really enjoyed.

If the spinning effect is what you’re after, I recommend checking out Tenga Spinners, as they’re much better at that thanks to their soft structure.


The exterior is made of a material that sort of feels like very stiff rubber. This means that the toy is compressible and you can squeeze it if you feel like you want more stimulation.

The only downside here is that because of the way the toy is shaped, you can only comfortably squeeze the middle part. Lower, and especially upper parts will require a lot more force and might not be very ergonomic, especially if you want to make use of the vacuum hole at the same time.

This situation would definitely require both hands, so a hands-free experience might not work for those who like intense sleeves.

How does it feel?

As far as intensity goes, I would say it’s somewhere in the middle. It’s not mild, but it’s definitely not crazy intense. Obviously, you can squeeze it for a stronger experience, but that can get a bit tiring if you strongly prefer intense sleeves.

Aside from that, the texture is quite good and offers decent stimulation. The sleeve itself is very soft and pleasant to the touch.

One more thing to note is that the exterior shell is rigid and non-seethrough, I would pay a bit more attention if you’re likely to exceed the insertion length of 5.9 inches (15 cm). 

Because you can’t see where the toy ends and there’s absolutely no flexibility length-wise, you can accidentally hit “a wall” which doesn’t feel great. This is especially the case if you’re going fast and unintentionally pushing it a little too far. Nothing tragic but it’s something to be aware of.

How to clean, dry

Cleaning Tenga Flex is as simple as cleaning any toy that can be easily flipped inside out. Take out the sleeve from the case and follow these steps:

1. Pre-rinse

Get your toy to sink or shower and rinse it with lukewarm water. Don’t flip it inside out just yet. This will do the initial “flush” which will clean most of the stuff out. It’s a bit less messy to do this step first.

2. Inside-out and rinse

This is the part where you deep clean the toy. 

Carefully flip the sleeve inside out and wash the texture. I usually start with warm water first, massaging each nook and cranny to make make sure there’s no lube or bodily fluids left.

I then use a little bit of liquid hand soap and repeat the process. Once you’re done, don’t forget to rinse off the sleeve with warm water so there’s no soap left.

This is also a good time to give a quick wash to the case itself. While it’s usually much cleaner, the case also tends to come in contact with some fluids, so it’s good practice to give it a rinse as well.

3. Dry with a towel

This step is optional, but it helps your toy dry more quickly. You can use either regular towels or paper towels, just make sure you use the kind that doesn’t leave any lint.

Gently dab the towel to clean off excess water. Don’t rub the towel as doing so can damage the texture.

4. Air-dry it

This is easy as Tenga Flex comes with a drying rack as standard. Simply flip the cap inside out and place the provided stick into a designated slot in the cap, as seen below.

Slide over the sleeve and leave it out in the open to dry. It can take anywhere from a couple of hours to a day to dry completely, depending on your environment.

5. Store

Once there’s no moisture on the sleeve, you can put it back into its case (use the provided stick to make this part easier). Leave the stick inside the sleeve and close the cap.


One thing worth noting about storage is that the toy doesn’t stay upright. If you’re going to keep it in a drawer or a box it’s definitely not an issue.

However, if you’re going to keep it on a shelf or on your bedside table do keep in mind that it needs to lay on its side and that means it can potentially roll off. Once again, not a big deal, but it’s good to know.

The Verdict

While Tenga Flex has its drawbacks, it can still be a great choice for people who want to experience multiple levels of stimulation and don’t want to break the bank.

If you don’t mind the limited insertion length and you like being hands-on with your toy, this might very well be the toy that you’re looking for.
