Fat sex doll manufacturers claim to “break the single pleasure mode”, but their touch parameters are still set based on male user survey data. An experiment showed that the ideal range of fat layer damping values for female testers is 37% wider than that of men, but existing products do not provide corresponding adjustment functions. The situation of full body sex dolls is even more paradoxical – when companies use “scientific data” to package perfect body shapes, they are actually using statistical violence to erase individual differences. This promise of technological democracy eventually became a new type of disciplinary tool.
