The lack of physical contact for three months after the divorce made me suffer from severe skin hunger. The warm silicone surface of the full body sex doll became a life-saving straw - every night when hugging its ergonomically designed waist and abdomen, the hugging force recorded by the pressure sensor gradually decreased from the initial mechanical 78N to 15N of healthy interpersonal contact. This tactile recalibration process is like rewriting neural memory with physical parameters. The fat sex doll became a metabolic supervisor - the built-in body fat analyzer would illuminate the swollen abdominal area with soft red light after I overeat. This silent reminder is more effective than any diet pills.
