What surprised me the most was the warmth of the robot sex doll. The built-in heating system creates natural body temperature, making the touch feel more real and intimate. This warmth combined with the soft, high-quality materials provides a physical connection that enhances the entire experience and makes it feel like more than just a doll. Some simple sex doll torsos can't achieve this level of intelligence, and sex doll torsos can't be as smart as a robotic sex doll!
