Sensory features play a significant role in enhancing the realism of sex dolls. High-quality sex dolls are equipped with realistic skin textures, body contours, and even temperature-sensitive materials to simulate body warmth. Some dolls incorporate soft silicone inserts or gel-filled features, such as breasts or buttocks, which provide a lifelike sensation during use. Additionally, some advanced models have built-in sensory systems that respond to touch, allowing the doll to react to pressure and movements. These sensory features create a more immersive and interactive experience, making the use of a sex doll feel more natural and engaging.
