Flexibility is a key factor influencing comfort and realism. Silicone sex dolls excel in this aspect due to their elastic and soft nature. They can bend, stretch, and move more naturally, mimicking the flexibility of real human bodies. This allows for more dynamic and comfortable positions during use. Inflatable dolls, on the other hand, tend to be less flexible. Their rigid plastic or PVC shells do not bend easily, limiting the range of positions and movements achievable. Although some inflatable dolls have adjustable features like inflatable parts, their overall flexibility remains inferior to that of silicone dolls. For users seeking a more natural, versatile experience with a wide range of movement options, silicone dolls are the superior choice. The flexibility of silicone enhances comfort and realism, making interactions more authentic and satisfying.
