The misconception that the skeleton is loose is that you can more easily manipulate the real sex doll in bed. This is not necessarily true, as the biggest difficulty in manipulating the doll on the bed is her weight. Even a 65-pound doll like me will need some effort to transition from one location to another. And the connection between her head and neck was a bit loose, so when I moved her head, her head always wanted to throw her face into the pillow first, which was annoying. Silicone dolls are completely different from teddy babies, who can change poses effortlessly. My real doll has finger lines and my doll has no finger lines. When playing games, I prefer to have no finger line, because by then I had to fix many finger poke on the doll. However, it does make interlocking fingers holding hands less pleasing. There are almost no wires on the baby’s feet. If the look is realistic, I would choose Insert. So far, all my Japanese sex doll are built-in because these conditions are not met.
