Fleshlight Stamina Training Unit Review

The Fleshlight STU is great for men having issues in bed with their partners. It is a lifesaver if you are struggling to last longer or tend to ejaculate too quickly. With this sex toy, you can learn to control your ejaculation better and at the same time enjoy the sweet sensation this fleshlight gives.


Like we said earlier, this sex toy is for men wanting to improve their stamina in bed. However, what you don’t know about the Fleshlight STU is that you enjoy more intense orgasms because it is very stimulating. If you want to have intense orgasms, this fleshlight is for you. The Fleshlight STU comes in three different models, Lady, Butt and Pure. They all have different textures but do almost the same thing. One can say that the difference is in its orifice. The three models come in the same size and there is enough insertable space for the average male penis in its sleeve. It works fine for men with a penis girth of up to 7 inches. It can feel a bit tight and uncomfortable for some, but the tightness only adds to its intense sensation. The pussy orifice model is also known as the Pink Lady model is one of the most preferred. It comes in a very simple design and with one texture. The whole chamber is surrounded by round raised bumps that will grip the penis at all angles during entry.

Sensation Options

This STU is specially designed to improve your orgasm techniques and maintain control. It gives you familiar sensations with its Speed Bump texture that you don’t reach the height of stimulation that will cause you to climax quickly. It is best for edging and allows you to hold back when you are about to climax so you can last longer.

It is a perfect training unit, but at the same time, it has some constrictions that can cause intense pleasure for the penis.

The inner chamber is narrow and gives a tight feeling which will stimulate your penis. When you thrust, the texture grips and massages the penis causing very intense pleasure. The Pink Lady model and Pure Hole model give similar sensations because they both have similar chambers. The best way to get more pleasure from this sex toy is to uses a little lube. It would make it easy for movement and also to feel all the powerful sensations the Fleshlight STU gives.


If you are using this stamina training unit for the first time, no need to fret, it is a very good sex toy. There is no best way to describe the amazing sensation you get when you use it. Each experience feels so amazing and will intensify your arousal. The bumps enhance your sexual stamina and will help you gain more control with your partner. It has an inner canal texture that catches the attention of anyone using it. What this amazing part does is stimulate your penis even when you haven’t thrust fully into the canal. The STU even feels more pleasurable when you run a little hot water through it before you start using it.

The warm feeling gives your penis a familiar feeling of being with a real vagina and the sensations are even ten times better. The tightness of the STU can be compared to having sex with a virgin or having anal sex. It can be a bit too tight for some people, but most people enjoy this feeling. Also, you can adjust the top cap if you feel it is too tight for you and make it to your preferred level.

The STU usually comes with lube, but if you exhaust it, you need to get a water-based lube so you can enjoy using it.


The STU sleeves are generally made from its patented pink SuperSkin material. This silicone skin feels like actual skin on your body, so you feel comfortable when thrusting. The outer case for some people is a problem because of the gold color but to most people, they are fine with it. The gold case has a good grip, but it is not discreet. It is made of plastic while the interior of the sleeves is made of silicone material. The silicone material is waterproof which makes it very easy to clean. The Fleshlight STU also comes with a starter lube and plastic rod to help you keep your sex toy in good condition.

The lady’s lips are very similar to a vagina and even looks pretty in its pink color. The clit and the lips are accurately proportioned so it fits right. The silicone skin is comfortable and safe on your skin. It won’t cause any irritation and it also aids in your stimulation. The material is also durable and can withstand pressure. It has no issue retracting to its original size.

How to use the Fleshlight STU

If you are using this sex toy for the first time, there is no need to worry. It comes with an instructional manual to guide you on how to use it. You will need the manual at the initial stage until you are fully comfortable using the device without any help. When using it though, it would help to take note of how long you last each time. The longer you last, will mean that the device is working for you.

The result is not always immediate but will take a couple of days or weeks sometimes before you notice any changes in your ejaculation time. This fleshlight trains your penis to control your climax. We recommend you use it every day to help control your ejaculation. It even has a shower attachment so you can have it as part of your morning routine.

The longer you use it, the better the results, and you can also combine it with some breathing techniques to help you before you get to the point of climax. You should also try its different speed and suction levels when using it. Also, try it with different angles and find which way works best for you.

The STU normally is easy to use even without the manual, so if you are already familiar with using other fleshlights, this one should come easy. The only difference between the STU and other Fleshlight sleeves is their texture. This stamina training unit is meant to overstimulate you with its hyper-texturized sleeves. Initially, you may climax immediately you use it because the sensations are so intense. However, that is the point of the training, so you can withstand it and overcome premature ejaculation.

If you also want to know how to use this device and get faster results, it comes with a free ebook with detailed instructions. You can follow the guide to help you last longer during sex. Nobody likes a partner who can’t last two minutes in bed, and it can be embarrassing. You can also get better erections and pleasure your partner when you are together in bed.


The bumps inside the sleeves are all over and need to be cleaned properly. It will take a certain amount of care to ensure you get out every deposit and leftover lube inside it. You can run water through it but you need to make sure it goes through both ends of the sleeve. You can also fill the sleeve with water and then cover both ends with your fingers shaking it to remove any difficult residue. You can leave it to stand so it gets dry and there is also the option of placing it close to a warm spot, but you shouldn’t put this fleshlight anywhere near a radiator.

You need to rinse the fleshlight thoroughly when washing so that every part of it is cleaned. It is not recommended that you use soap because it can damage the sleeve but there is a special solution that Fleshlight sells, i.e., the Fleshwash antibacterial cleaner which you can use to clean your sex toy. In the alternative, you can use a little isopropyl alcohol to clean it. You only need to use these cleaners once in a while but not every time you use your device. The only challenge with washing your fleshlight is the drying part, which takes a longer time. Drying can take as long as a full day. You should find a convenient place to let it dry.

You shouldn’t keep your fleshlight wet because it will cause mold to grow in it and make it susceptible to bacteria. The makers of this sex toy recommend that you use its Renewing Powder to keep your sex toy looking fresh. If you don’t have this, the alternative will be cornstarch.
