The Berman Dilator Set is a vibrating kit with 4 different sizes of dilators. We love that this set offers vibration, because vibration helps to increase blood flow, and also puts some focus on adding pleasure to your dilation exercises. The smallest size is attached to the base of the toy, and there are three separate plastic sleeves that graduate in size. A unique interlocking system secures your desired size to the base. Also included in the set is a soft, textured sleeve made of thermoplastic rubber (TPR). [[[How It Works]]] Dilators can help decrease pain and discomfort during intercourse and to increase sexual pleasure in your life. Most people use dilators in order to maintain or increase the elasticity of the vaginal opening. There are many different ways to do dilation exercises, and we strongly recommend consulting your doctor of physiotherapist before using dilators, in order to make sure you have the best instructions for your body. This dilator set is best suited for active dilation, the firm plastic and handle make it easy to hold and move. Dilation exercises work best when you are relaxed and using a lot of lube. Try to make some uninterrupted time to use your dilator set. Many people find that taking a hot shower or bath helps to relax them a little beforehand. The frequency with which you use them will vary from person to person. Focus on deep pelvic breathing – also known as "reverse kegels" - this breathing helps relax the pelvic floor muscles. Use the smallest comfortable dilator to gently stretch in different directions. Picture the vagina as a clock and apply a gentle stretch at each number on the clock. Stop if you experience any pain and switch to a smaller dilator next session.
