Creating a realistic and enjoyable experience with a sex doll involves several key features. High-quality skin materials like silicone or TPE are essential, as they replicate the softness, elasticity, and temperature of human skin. Textured surfaces, such as detailed skin pores, veins, and realistic coloration, further enhance visual authenticity. Additionally, features like movable jaws, expressive eyes, and realistic facial features contribute to lifelike interactions.

To heighten tactile sensations, some dolls incorporate internal heating systems, providing warmth akin to a real body. Internal skeletons with multiple joints allow for natural positioning and flexibility, supporting a wide array of poses. For increased comfort and realism, some dolls include features like soft padding, realistic weight distribution, and flexible limbs that respond naturally to touch.

Moreover, auditory or responsive features such as voice modules or touch sensors can enhance the immersive experience. The inclusion of scent-emitting systems, or the ability to customize body scent, adds another layer of realism. Overall, combining high-quality materials, detailed anatomical features, and interactive elements results in a sex doll that offers a more authentic, pleasurable, and emotionally satisfying experience.
