I've been looking for information about it. It is very strange to me because I think it exceeds fantasy. I found these facts:
These dolls are called
Datch Waifu and they come from Japan. Their resemblance to a real woman is intimidating, but they are obviously not real. They are made of latex, vinyl and silicone, they have a metal skeleton, joints and the only thing natural is their hair. What does resemble a real woman is that no two are alike. The customer is the one who customises them: height, waist size, breasts, skin colour, butt and facial expression. They can even have voice and motion sensors with preset responses for all kinds of situations. In addition, if the customer wishes, they can buy clothes for their dolls, wigs, make-up and all kinds of accessories.
These sexdolls have been produced in Japan for 10 years and are very successful. Some of the reasons given by consumers are the fear of contracting sexually transmitted diseases from a real person, the little time they have to meet people due to the large amount of time they spend working or the little time they have to spend with their families, which is why many men lose the ability to interact with their wives and resort to these dolls. Here you have more examples of
Japanese sex dolls.
