This long and smooth urethral sound is perfect for the special stimulation of the penis. With a bit of practice, its 6 mm can be easily inserted into the urethra, providing a sensation like you've never felt before. When Slim Finn is thinned out, it gets really thick for you. With its slim and lightweight body, the urethral dilator brings the entire range of electrostimulation to excitingly unfamiliar places. Its gently rounded tips and the seamlessly smooth transition between the poles not only give it an elegant appearance but also make insertion into the urethra easy with a little practice and lubricant. Once Slim Finn is in place, it combines the bittersweet stretch from within with the endless teasing of impulses into a unique symphony. Just a few centimeters in, this compact Mystim E-Stim dilator isolates the two poles. To activate them, you need a stimulation device. Then the electrical stimulation begins. Even during stretching, the stimulation tingles, tickles, or pulses significantly. The experience in the tube becomes even more intense if you warm Slim Finn on the heater or cool it in the refrigerator before use. If you want, the tingling, pleasurable sensation can kick in for hours. You can vary and intensify the stimulation so that you are quickly driven to sensational peaks, or just enough to hold off from climaxing for a few seconds. It all depends on your preferences and your stimulation settings. For cleaning, simply use water and a mild detergent, as well as a skin-friendly disinfectant at regular intervals. After it has completely dried, it is ready for the next big use.
