I was immediately intrigued by the vibrant blue and white swirl sea mammal design of the Climax Silicone Splash Dolphin vibrator. Although the toy is nearly six inches long (and just over one inch thick), only four inches of the Dolphin can be used for insertion, so deep thrusting is out of the question. For those who prefer a smoother texture, the silicone offers a soft, flesh-like feel.
