Maintaining the flexibility of your sex doll’s joints is essential for realistic posing and longevity. Regular maintenance begins with gentle handling; avoid forcing joints beyond their natural range of motion to prevent damage. Using a small amount of silicone or petroleum jelly on joint hinges can help keep them supple and prevent stiffness caused by dryness or dust accumulation. When adjusting joints, do so slowly and smoothly, ensuring no sudden movements that could stress the material. Periodically inspecting the joints for signs of wear or looseness allows you to address issues early. If joints start to feel stiff, applying a light lubricant designed for soft materials can restore flexibility. Additionally, storing your doll in a neutral position—neither fully extended nor compressed—reduces strain on the joints and maintains their shape. Keep the environment where the doll is stored clean and free from dust, which can settle into joints and impede movement. Gentle exercise of the joints after long periods of inactivity can also help maintain their flexibility. Remember, patience and regular care are key to ensuring your doll’s joints remain supple and functional for years to come.
