Fleshlight STU Review 2024 | Does It Really Work?

Featured image

I receive many questions about the Fleshlight Stamina Training Unit (STU) from my readers. These questions don’t surprise me since 1 out of 3 men suffers from premature ejaculations, and the company is marketing this product as a solution.

But does it really work? To find out, I decided to buy one to see if it REALLY lives up to the hype. Follow along as I unravel all the secrets of this popular sleeve!

Key Takeaways
4 out of 5 stars

I must say that the STU was very different from other Fleshlights I have tested. The texture felt distinct from start to finish, especially on my penis head and the glands just below. The sensation from each raised bump was intense, and you need to take shorter breaks, which I thought increased my sexual stamina over time. I have used it for over a year, and I’m definitely seeing some improvements in the bedroom. But I found that you need to keep doing these exercises otherwise the stamina improvements will fade away over time.

Who Should Try It? Anyone suffering from premature ejaculation (PE) will receive great value from this product. It’s also excellent for penis owners experimenting with edging or longer masturbation sessions. In addition, well-endowed guys will appreciate that it’s not as tight as other Fleshlights.

Who Can Skip It? It’s not a great first-time sleeve as it’s quite intense. If you’re a beginner, I recommend buying Flight Pilot or Quickshot Vantage instead.

First Impression & Features

The Fleshlight Stamina Training Unit package includes the following;

  • The iconic gold case.
  • Superskin Sleeve with Lady Orifice.
  • Instructions for Use and Care.

  • A small bag of Fleshlube.

So, what was my first impression of the Stamina Training Unit Lady? Elegant and classy. From the shipping packaging to the finer details.

Some other reviewers complained about the gold color, but I loved it. Who cares if it’s not discreet? You’re not going to have your sex toys around the house for everyone to see, right?

Packaging

Like every other Fleshlight purchase I’ve made before, the company delivered the Stamina Training Unit in a discreet plain cardboard box. This helps to keep things on the low, especially for people living in shared spaces or those with eavesdropping neighbors.

The packaging underneath looks nice with a glamorous yet classy design. The front is windowed, allowing you to peep inside without breaking in. The other side spots helpful information, including showing the internal texture and some wise words on why you’re lucky to have bought the Training Unit. The back also details the specific color, orifice, texture, and case of your masturbator.

To get to the Stamina Training Unit, break the tamper-proof seals and open the flaps. The gold trainer sits comfortably inside with a cushion-like carton holding it in place. There’s also a handy instruction manual on how to use and care. Finally, Fleshlight made sure I didn’t have an excuse not to use it immediately with the cute little water-based lube. Check out my Fleshlight buyers guide for more tips.

Design

Fleshlight uses the patented Real Feel Superskin material on all masturbators, and the Training Unit is no exception. The material feels like human skin with a consistent blend of squishiness and firmness. It’s also hypoallergenic, phthalate-free, super flexible, affordable, easy to maintain, and very durable.

Superskin feels sticky initially, but cleaning the masturbator with warm water and a toy cleaner usually washes off the tackiness. I also have some Renewing Powder in my bedside drawer, which I always sprinkle after cleaning.

The gold Fleshlight case gives the masturbator a luxurious feel  you usually don’t get with other models. It’s made of hypoallergenic plastic, which is durable and easy to clean. I especially liked the well-sculpted body with resourceful grip lines on the stem to improve my handling. The sculpting plus the encrypted Fleshlight name and logo make it even more attractive and grippy.

The Lady Training Unit features a pink vagina that looks like the real thing, including a clitoris. During my testing, I particularly liked the good blend of resistance and acceptance it offered. And the orifice also gave me slight resistance during penetration and held my penis’ shaft in position once I was inside. Overall, I felt the designers did an excellent job with the orifice!

Note: Fleshlight also sells a Pure version that doesn’t look like a pussy. It’s just a hole. Pure is a good choice for men looking for something more discreet or gay guys who don’t want a vagina.

Sleeve Texture

The STU is lined with bumps throughout the entire sleeve. The nodes stimulate your dick as you stroke the masturbator, teasing you in ways your bare hands will never be able to.

The texture and tight tunnel make it difficult for newbies to use it at a fast pace. The stimulation is intense, and only experienced players can go high tempo with this one. However, as you get used to the intense sensations, it becomes easier to dive without bursting out in seconds.

And why torture yourself with the studded texture? You might be asking. If you can withstand the teasing, you’ll surely last longer with a partner. The STU trains your body and mind to withstand the trickiest environment so that you can do even better and last longer in bed.

Note: You have to remove the sturdy tube inside the sex toy to use. I recommend soaking the sleeve in warm water for a few minutes before use. The warmth makes the experience super realistic, feeling just like a vagina.

The Bottom Cap

The STU’s golden case has a removable bottom cap you can twist to regulate the vacuum suction effect. If the sleeve feels too tight, you can either loosen or even remove the cap. Similarly, if you need more suction, tighten the bottom cap or close it completely.

The bottom cap lets you hold on better, even under pressure. It also allows you to gradually progress in terms of the suction power you can take when practicing to last longer in bed.

How Does The Fleshlight STU Feel Like?

During my testing, I felt Fleshlight STU was different from other sleeves I’ve used. The intense texture felt distinct from start to finish, especially on my penis head and the glands just below. The sensation from each raised bump is intense, and I can imagine it’s pretty hard to control yourself as a first-timer. In addition, it spread the sensations evenly around my penis shaft and head.

Further, it felt as good on the up-stroke as it did on the down-stroke. This effect is uncommon since most toys feel sweeter during penetration than retraction. I also liked that it’s not as super tight as Stoya and other sleeves. Larger men will be able to use this product without feeling uncomfortable.

Like other masturbators with vertical texture, the STU delivered another type of sensation when I rotated it. Simply slide your erect penis into the sleeve and slowly slide the masturbator sideways (clockwise/anti-clockwise). Feeling all the rounded bumps hug your cock entirely while changing the direction and speed gets you a different sensation!

So how fast did I cum? Well, surprisingly, I did last fairly long with this masturbation sleeve. During my first attempt, it took about 2-3 minutes. In the next round, I managed a whole five minutes. Compared to other reviewers, this is a fairly long time.

I think the reason is I don’t have any stamina issues. Plus, I’ve used tons of Fleshlight models in the past. That said, I can confidently say this sleeve will be helpful if you have these issues. It’s just that intense.

Pro tip: Use the Stamina Training Unit with the Fleshlight shower mount for a 100% hands-free experience!

How Can I Use It To Improve My Stamina?

As with your body, exercising is the best way to boost your stamina and jog your energy levels. The STU works your penis out while relaxing your mind and body for long-term resilience benefits. So, here’s how to use the STU to improve your sexual stamina:

1. Learn to stop before you cum

Easier said than done. Right? Well, I didn’t say that it would be easy. Did I?

The practice is called edging or peaking, and you halt just before you ‘jump off the cliff.’ Simply stroke your junk with the Fleshlight STU and stop when you’re about to climax. Take a 30-second break before stimulating yourself again, and eventually stop when you’re about to orgasm again.

Continuous edging practice makes you more aware of your sexual urges, ultimately bringing mindfulness during sexual intercourse. It trains you to last longer by taking charge of your orgasms. Experiment with different angles, levels of penetration, and rhythms for better results.

2. Breathing Techniques

When using the Stamina Training Unit, breathing is important because it helps you maintain your composure. During my research, I found steady rhythmic breathing reduces the chances of getting too excited too quickly. Control your breathing pace and enjoy each stroke as it comes. Also, ensure you’re relaxed and anxiety-free before starting the training.

3. Adjusting the Suction

Another technique you’ll have to learn is how to adjust the suction during play to enhance your experience. Training with the correct suction pressure not only avoids straining your penis muscles but also promotes positive results. So, loosen or remove the screw cup and tighten or close it to attain the proper suction.

Final Rating4 out of 5 stars

That’s it, folks! The Fleshlight Stamina Training Unit Lady is a unique masturbator that seeks to elevate your masturbation sessions and sex life. What’s so special about the masturbator is it goes above and beyond the classic ‘freeing your hands’ call – it helps you improve your sexual stamina issues and last longer in bed.

With techniques like edging, rhythmic breathing, and suction control, the STU can revamp your sex life in ways you never thought. You see, the beauty is it’s just as resourceful to single users as it is to couples. The masturbator trains you to control your mind and body to delay your ejaculation and improve your bedroom skills.

Trust me! I used it for a while before I wrote these Fleshlight STU reviews, and I’m already noticing some changes. Sandra sees the changes, too. I bought the masturbator without her knowledge, and I vowed only to come out clean when she saw the difference. And so, here we are. I delivered the news to her, and she’s ‘never been prouder” of our love life.

Pros

  • High-quality design and human-like Superskin material.
  • The length and girth will accommodate men of all sizes.
  • Intense, contoured sleeve.
  • Variable suction effect.
  • Easy to clean and maintain.
  • Affordable price tag (cost $69.95).
  • Classy gold case.

Cons

  • Some guys may find the case quite big and indiscreet.
  • Not very realistic. (But you’re not buying it for realism).
  • It doesn’t have the variety of other models, such as Stoya.

How To Clean Fleshlight STU?

Cleaning is one of the factors that you’ll have to consider before making the purchase. How long do I need to be at the sink? What’s the best cleaning method? What are the implications of different cleaning methods? For the Fleshlight stamina trainer, you don’t have to work yourself up – cleaning is easy, and you only need warm water, a sex toy cleaner, and running clean water.

I like cleaning it as soon as I’m done using it, and the strategy has proven to work. Firstly, it’s easier to clean it before the body fluids and dirt become attached and harder to come off. Secondly, cleaning immediately means your masturbator will always be ready whenever you are.

So, stop at the sink and run clean, warm water through the sleeve to remove body fluids. Mix the recommended cleaner with water and clean the masturbator before rinsing with running clean water. For the case, use a damp cloth to wipe off any visible dirt marks. Remember to air dry the sleeve and the case before putting them back together. Alternatively, you can use a dry, clean towel.

Note: I recommend using water-based lube only with the STU. Unlike other types of lube, the Fleshlube water-based model doesn’t affect the sex toy’s material. It’s also latex-friendly, and you can use it with a condom if you want to simplify the clean-up process. Lastly, unlike oil-based and silicone-based lubes, this one doesn’t stain your bedding.

Are There Any Good Alternatives?

Stoya Destroya

Stoya Destroya has varying textures to elevate your experience. The sleeve is part of the Fleshlight Girls series and has uniquely positioned rings, pleasure domes, fangs, and big bumps. It gives you all-around stimulation, and with the proper stamina improvement training, Stoya Destroya can be just as resourceful. In addition, it comes with a screw cap to adjust the suction.

Endurance Fleshjack (The Gay version)

Endurance Jack functions the same as the Fleshlight STU; the only difference is that it’s marketed to gay men. Why is that so? Because the brand appreciates diversity and developing a one-for-all product didn’t sound right. This masturbator spots a varying texture, a grippy case, and, most importantly, a replication of a human-like ass hole.

So, if you’re a gay guy, you don’t have to force yourself into using a masturbator that isn’t appealing to you. The Endurance Fleshjack is built just for you!
