Technological progress is the key driving force for consumers to choose sex dolls USA. American manufacturers have invested a lot of R&D resources to optimize silicone materials and artificial intelligence functions to ensure that the products are world-leading in safety and interactivity. For example, new models have added body temperature simulation and voice response systems to enhance the realism of the user experience. These innovations not only attract first-time buyers, but also encourage old users to upgrade.
