The problem with putting a Japanese sex doll on the bed is that you cannot effectively leverage when you lie down. The doll’s full weight was dragged on the mattress. So what you can do is find the pivot point and then you have to reposition the head, arms and legs every time. Therefore, hugging on the bed will develop from one static position to another, and every time the doll moves significantly, it needs to do some work.
With a real girl, the whole thing will become more. It is still good with dolls, but needs more elbow grease. I think the inserts are okay, but their inserts don’t look realistic in the vagina. It is the only company I know to make a very realistic insertion vagina. Cleaning built-in components is more tedious than inserting components, but I don’t mind because sex doll feel great and realistic.
