Stamina Training Unit
What guy doesn’t dream about being that one stud that keeps on pounding his girl until she’s begging him to climax inside her. The STU promises not only to improve your sexual stamina, but also to raise the intensity of your orgasms. Now let’s take a closer look at the product.
STU design: The Stamina Training Unit Insert has a variable diameter that ranges from 0.45 to 0.6 inches, which makes it one of the tightest inserts of ILF.
The inside is covered front to back with large-sized bumps which are placed very close to one another, forming a dense texture. The STU’s patented Real Feel Super Skin is soft to the touch and feels very skin-like. It’s probably about as close as you’re going to get to human skin. The video below gives you a close look inside the STU.
Flashlight experience: Compared to other more complex inserts like the Destroya, STU’s inner texture doesn’t really look like much. Nevertheless it feels amazing. The dense bump texture applies remarkably intense stimulation on the penis. The STU texture feels like an army of fingertips that massage and caress every single square inch of your head and shaft, replicating the incredible sensation of sexual intercourse. Additionally the STU has a strong suction effect, which heightens the stimulation and can be adjusted with the end cap.
What makes the Stamina Training Unit so special is that the harder your penis gets the better the texture feels wrapped around your cock. The whole experience becomes more sensitive, especially around the head. That’s one of the reasons why it’s so damn difficult not to come right away.
In order to not blow your load right away, you have to go slow. Pumping in and out might feel awesome but you are not going to last very long. Also the longer you last the more intense the orgasm feels. The STU encourages you to go as close to the edge as you can, and then slow yourself down, enjoying the gentle suction and the texture rubbing against your penis. This is exactly the skill that you can improve by training with the Stamina Training Unit because you will gain control over your own sexual arousal which is key for sexual stamina.
The Stamina Training Unit is without a doubt one of the most intense Fleshlights ILF has to offer, and one of my personal favorites. The textures stimulation and the gentle suction replicate sexual intercourse better than anything else on the sex toy market, and as a bonus will provide you with the stamina you always wished you had.
