Fleshlight: Stamina Training Unit (STU) Review

Out of all of the Fleshlights that are out there, I chose to review the Stamina Training Unit for the simple fact that it is the number one best selling and most favorite model among most men. Their patented SuperSkin masturbation sleeve, and their stamina unit design to help men last longer, has definitely made it well deserved for Fleshlight to have the title of #1 selling male toy in the United States.

Texture and Purpose

The Fleshlight Stamina Training Unit is designed to have small nubs that surround the inside of the male masturbator. These small nubs are going to give you a very tight fit and texture to simulate the incredible sensation of having sex with a woman. Using this toy often enough will help you find your rhythm and discover how to achieve peak sexual performance. Meaning, it will help with stamina when actually having intercourse with a woman. This toy in hopes will help you last longer and stay harder longer during sex, so that you don’t ejaculate too quickly.

The high quality materials they use are very popular for the fact it is very lifelike. It makes it one of the most realistic feeling male masturbators on the market right now. Although the material is very soft, it is also very durable. As long as you are using water – based lube only, and make sure to clean it properly (see bottom of article for cleaning instructions) your Fleshlight will last you years.

A lot of men think you have to use things like pills, creams, or even cock rings (which can feel like a death grip to your penis) to help them last longer – and they are totally unnecessary. The Fleshlight Stamina Training Unit is the fun and safe way to work on lasting longer.

Patented Case Design

These male masturbators were designed to look like the old school standard flashlight. Not only is it a little more discreet in this case, but it is actually a patented design that is half the reason these Fleshlights are as good as they are. The case is great for the fact that not only is it easy to put the sleeve in and pull it back out, but it allows for the SuperSkin to be manipulated, pulled and pushed in different directs during use, but maintains proper pressure and resistance throughout your entire session, and protecting it from getting ruined while giving you an incredible experience in the process.

They have recently added multiple vents to the smaller end of the case, so that if you want less suction you can turn the little cap at the smaller end of the Fleshlight case, and it will give you less suction. If you want the most amount of suction possible just keep the cap at the bottom completely screwed shut so that there is no air getting out.

Most Fleshlights will use the same outer hard case, so if you decide you want to try a different texture than the Stamina Training Unit, you can just purchase a different sleeve instead of buying the whole thing. You just have to be careful, some Fleshlights are more compact than others.

When finished using the Fleshlight you will take the toy completely out of the case and flip it inside out. Rinse the material well under luke warm water and use the Fleshlight Fleshwash Anti-Bacterial Sex Toy Cleaner to spray over your toy, and work into the SuperSkin.

This wash is anti bacterial and won’t have any fragrances, or alcohols that can break down your toy and make it fall apart faster. After you finish working the wash into the material rinse it off and let it dry.

Cleaning Fleshlight Stamina Training Unit

After you let it dry that is when you will use the FLeshlight Renewing Powder. The toy must be completely dry before applying the powder, otherwise it will get caked on there and you will have to rewash it all over again. So, when your Fleshlight is completely dry you will sprinkle the renewing powder onto the your toy and this will pull out any extra moisture left in your Stamina Training Unit, this way when it dries it won’t get sticky, or start to have little pieces of the material fall off.

Then you are ready to store it! Just put it back into the hard case and put it away for next time!
