The realism of advanced sex dolls has significantly improved thanks to technological and material innovations. High-quality silicone or thermoplastic elastomer skins provide a soft, warm, and lifelike surface that closely mimics human skin. Internal structures, including articulated skeletons and responsive motors, allow for natural movement and positioning. AI-driven features enable dolls to respond with conversational cues and emotional expressions, adding a layer of psychological realism. Many users report that the tactile sensation, combined with the visual and auditory stimuli, creates a convincing experience. However, while the external appearance and responsiveness have reached remarkable levels of realism, some aspects—such as temperature regulation and nuanced emotional responses—still have room for enhancement. Overall, the feeling of realism varies among models and users, but ongoing technological progress continues to narrow the gap between fantasy and reality, making these dolls increasingly indistinguishable from real human interactions.
