Damn! This is one hot masturbator! Although I’m still a newbie at using sex toys to get off, I’ve become addicted to finding new places to put my cock. Not wanting to be the only guy on the block without a full-sized Fleshlight (I’ve also got the Fleshlight Lady Lager but that is a bit smaller), I just had to try one and looked at some of the possibilities. The Fleshlight Stamina Training Unit (STU) immediately caught my attention especially since it purports to help men increase endurance and last longer. Just as exciting is that Fleshlight recommends practicing to gain improvements (no, I’m not going to add jackoff sessions to my calendar) and that, of course, is certainly an enjoyable and worthwhile endeavor.

It is very important to prepare the Fleshlight before its first use. When the STU is packed for shipping, a plastic rod is inserted into it (apparently to protect it during transport): this MUST BE REMOVED FIRST. Failure to do so could cause great pain and suffering to your cock! Avoid a dick disaster and make sure that the shipping rod is removed! The manufacturer also suggests taking it apart and letting the penis sleeve soak in warm water for a few minutes to make it feel more lifelike. It was already a balmy day when I first used the STU so this step wasn’t necessary.

With the initial nitty-gritty out of the way, it was time to take the Fleshlight for a test drive. I lubed it up (the STU requires a fair amount of water-based lube) and explored the interior with my finger – just to get a sense of what would be lurking ahead, greased up my manmeat (something I usually don’t do when taking things into my own hands but with sex toys, I find that no matter how much pre I make - and I make a lot - the toys still want a lot of lube), and ever so carefully slid my cock past the STU’s Superskin pussy into the hidden recesses of this enormously stimulating penis pleasure palace. Wow – it was absolutely phenomenal! Woof!

I really wasn’t prepared for how incredibly stimulating it was – the interior of the STU is specially designed to “provide the most intense and pleasurable training experience possible” and Fleshlight did a very good job in doing so. I found that it was necessary to take things very slowly to avoid a major blowout right away (although that's always the ultimate goal). I’ve got to admit that I lost control very quickly and, because it was my first use, I just gave in and blew a huge load right away. Of course, I understood that I’d have to practice a lot in the future so I wasn’t too worried that this would be a onetime shot.

In order to review the STU properly, I’ve since used it several more times and have found that the STU has consistently been very stimulating although I certainly made conscious efforts to take more time. Yes, it’s tough to do so considering how wonderful the STU feels caressing your cock but it is possible. The important thing for me was to just slow down a lot and even giving my cock a break by removing it from the STU (yes, my penis and I ending up arguing – it said MORE and I had to say NOT YET). In the end, my dick always wins but that’s okay!

The outside of the STU is constructed from rigid plastic. It is rather large but has sufficient places to hold on to while masturbating, even if it gets slicked up with some lube. The interior contains a textured Superskin pussy with a realistic love tunnel that is feels like real skin. The penis sleeve is phthalates-free (a substance that is used to make many plastic products soft but can cause health problems) and features a specially designed interior will send shivers of pleasure up and down your love muscle.

When removed from the exterior container, the penis sleeve is extremely flaccid and is rather fun to play with due to its soft texture. There was just a very slight smell to it and no perceptible taste except for something that seems to resemble corn starch (not that I eat raw corn starch to really know).

The STU follows the “classic” Fleshlight design: the outside container looks like a very large flashlight. The exterior is approximately ten inches in length and has a four inch outside diameter at the widest point. When the lens end of the Fleshlight is removed, a pink Superskin pussy is revealed while the opposite end contains a cap that may be tightened or loosened to adjust the amount of suction on your cock during use. It is quite a bit easier to insert your boner into the Fleshlight if the cap is loosened first – after that, experiment and enjoy the sensations! The STU is large enough that it should adequately accommodate almost all dicks, regardless of size.

This masturbator is designed to make men cum as quickly as possible with the intent to see how much they can resist the need to blow their loads. There are many ways to increase your stamina: you can slow down, adjust the amount of trust into the STU, taking your dick out and then reinserting when a bit more control returns, etc. You can also take some time and rub your dick on the pussy lips - that also feels and looks great! My own experience is that you will need to concentrate to keep this Fleshlight from winning too soon.

One thing I noticed right away is that the case of my STU is made from a gold-colored plastic instead of the black color that was pictured when I ordered it. Although I would have preferred black, I can live with the gold even though I can’t ever recall seeing a real flashlight in that color. Just the same, the large size of the Fleshlight is much too large to be mistaken for a real flashlight and, therefore, isn’t exceptionally discreet unless you were looking at it from a distance. Of course, uncapping the pussy end reveals hidden treasures that no real flashlight would contain!

The Fleshlight STU is a very simple masturbator that only has a few parts: an interior Superskin penis sleeve and an exterior plastic case with removable caps covering each end. The “lens” cap serves primarily to protect the vagina when not in use while the cap on the other end has a specific function; to control the amount of suction on your cock while masturbating. Loosening the cap decreases the amount of suction while tightening it increases suction. During use, the STU does make some slurpy squishy sounds as it slides up and down your erect penis but unless someone else is in the same room, I doubt that it’s really that noticeable.

While this masturbator is fairly large and, arguably, somewhat discreet, I don’t think I’d carry it on a plane with me – especially since airport security has a tendency to ask passengers to turn on other devices (such as laptops and other equipment). While I doubt I can turn on a Fleshlight, it sure turns me on and I really don’t want to prove that it’s functional with a line of impatient passengers watching just so that security can get a few more jollies. It would probably be okay to place it in checked baggage but don’t blame me if you get caught in an embarrassing moment if you try!

As with all Fleshlights, the STU is made from Superskin, a porous material that does a great job of emulating the largest organ on your body (sorry guys, but that really isn’t your dick; it’s your skin) although it requires a little bit of special care to ensure a long life. First of all, use only water-based lubes on your Fleshlight and your dick, use of oil or silicon-based lubes can cause your STU to prematurely age. It is recommended that plenty of lube be used in order to prevent skin irritation (penis burn).

Similar care is required when cleaning. The penis sleeve should be removed and warm water run through it. Some of Fleshlight’s literature notes that this will help to “remove fluid deposits” (now, what could those be?) and a small amount of isopropyl alcohol may be used if desired. Soaps and detergents should never used; they can cause the Superskin sleeve to deteriorate. Unfortunately, it is unlikely that dermatologists will agree to treat your Fleshlight if it gets ill so treat it with care.

The STU must also be towel or air dried thoroughly. Because Superskin is porous, it is critical to make sure that it is completely dry before returning the sleeve to the hard exterior case otherwise it could get moldy (ugh)! Never stick your dick in a moldy Fleshlight (and I’m not about to try it just so I can let others know what might happen). For this same reason, the STU should not be shared with others as who knows what other kinds of nasty things might lurk on its surface just waiting to find a new home. After its first use, the Fleshlight is all yours! Once dry, users may also want to apply a small amount of cornstarch to keep it feeling smooth and silky for your dick. It has been suggested that a a paint brush be used to apply the corn starch in order to prevent a mess. Trust me, the first time I tried to apply a little cornstarch, I made a real mess (no, I’m not talking about those allusive “fluid deposits” that the manufacturer suggests finds their way into the Fleshlight).

If I have one criticism of Fleshlights (not just this one) is that they do take a bit of time to clean. I've found that taking a shower together is often one way to solve this problem and my STU has never complained.

The Fleshlight arrived in a very discreet and generic USPS Priority Mail box. Inside was a metal container that serves as the STU's home. I was a bit disappointed the container was dented but, fortunately, the Fleshlight was in pristine condition and I’ve been able to sufficiently repair the can. The word “Fleshlight” is printed in bold on the canister along with silhouettes of several voluptuous babes that are very similar to those that might be found on the mud flaps of many big rigs (I’ve never quite understood the connection between the two unless female mud wrestling is something that truckers have a special affinity for). In addition, a small photo of the Superskin vagina and brief description of the Fleshlight are provided. Although the packaging isn't exceptionally discreet, the can does serve well for storage.

Inside that can, the STU was sealed within a plastic bag that also contained a small sample of lube. The word "Fleshlight" is molded into the gold-colored plastic case. The size, color, and even the shape are clues that it really isn't a discreet flashlight but something else.

Having now used this masturbator several times, the Fleshlight STU continues to give an orgasmic experience! (Is there anything better than that?) The sensations are phenomenal and my penis is very, very happy. One advantage that Fleshlights have over real flashlights is that they don't require any batteries. The only problem is, you will wish your dick had batteries because the STU will drain all of its juice and you'll need to recharge often. Too bad that this toy doesn't come with a recharger.

I suspect that many men will find this to be an extraordinarily stimulating masturbator and will need to take things very slowly while using it to in order maintain some control unless, of course, the intent is to blow a load very quickly. I found it effective to take a few short breaks from the STU and find other things to do with my cock until I could handle more of the intense sensations that this Fleshlight provides. Although cleaning it is a bit of a pain, the incredible masturbation sessions make it all worthwhile. Most importantly, your dick will also be very happy.
