All of the masturbation sleeves are made from a patented material called Real Feel Superskin – it s precise mixture of latex silicone with a little bit natural gum – rest of substances are kept in top secret. The STU is tighter, more intensely pleasurable, and just as discreet as the original Fleshlight, and comes in a visually stunning, realistic skin tone. Once you know what turns you on, you can communicate with your partner. I have a theory that it either 1 moves a lot of it into the back of the product or 2 that the patented material warps all modern lubrication into a build your own flesh light different time space dimension that humans have yet to discover. What would a much the same toy be for men. But being a woman walking into a mans place was intimidating. For us, couples got in for the build your own flesh light same price as one man.
