Using this Rock Candy Suga - Daddy 7 - inch dildo is easy. First, apply some water - based lubricant on the shaft and the area where you want to use it. If you want to use it on a flat surface, press the suction cup base firmly onto the surface to make it stick. You can also attach it to a strap - on harness for hands - free play. When using it, focus on the areas you want to stimulate, like the G - spot or P - spot, and use slow or fast motions according to your preference. As for maintenance, after each use, wash it with mild soap and warm water. Make sure to dry it completely before storing it in a cool, dry place. Don't use oil - based lubricants as they can damage the silicone material. And always check the suction cup and the overall condition of the dildo before each use to ensure it's safe and in good shape.
