Are sex dolls realistic now? But sex dolls weren't very good at first. Sex dolls, born as a tool for human masturbation, are said to be born during World War II. According to various sources, Hitler is sometimes referred to in a way as "the man who gave birth to sex dolls."
There are currently two theories about the relationship between Hitler and sex dolls. First, it prohibits Hitler from marrying non-Aryan women to ensure the purity of German descent. Sex dolls; the other said that Hitler was to prevent the spread of sexually transmitted diseases in the Nazi army, so he secretly ordered the SS commander Himmler to develop sex dolls.
The study ended in Nazi failure before it was completely successful, which may have been inspired, and Germany began to sell similar sex toys in the 1950s.

Inflatable doll
In the 1970s, sex dolls began to enter the stage of commercial development.Japan has developed a plastic inflatable body masturbation device. It is also called an "inflatable doll" because it is very similar to an inflatable swimming ring. It can be folded and stored at ordinary times, and can only be transformed into a human body after being inflated.
In fact, the inflatable dolls of that era were not "human-shaped women's dresses" called "human-shaped balloon toys", but simple and crude balloon toys. Compared with the inflatable mascots in front of shopping malls today, these inflatable toys are more humane in appearance, with one or two ventilation holes.
But despite this, with the advent of inflatable dolls, most consumers have long felt bored, especially when they were launched in Japan. Especially the sales are very hot. For example, when floods hit Australia in early January 2011, two 19-year-old children came to the rescue with an inflatable doll as a lifebuoy.

This is a doll that is easy to carry, but it is useless.
One of the development trends of human invention is simplicity and intelligence. In the 1980s, there was still a "palm-sized doll", which is still widely spread today. It is almost the same as a big hollow banana. It is very easy to use, easy to carry, and easy to hide. It has become a product that many consumers are rushing to buy.
But the problem is that such a small doll is not much different from masturbation. After all, most people want a full hug, not just a palm.
More realistic and beautiful simulation dolls
In the late 1980s, a sex doll appeared. At this point, the sex doll began to approach the simulation. In the beginning, One Piece's whole body was hard, with sharp edges and corners! Moreover, their attitude is fixed and single, and cannot meet the diverse needs of different groups of people.
In order to overcome these shortcomings, people developed a prototype of a simulated doll in the early 1990s, that is, a composite doll. Different parts of the doll's body can be disassembled, allowing you to pose in different poses to meet the needs of different people.
In addition, their faces have become beautiful, taking care of people's aesthetic needs to a certain extent. However, there are still shortcomings in the details, such as the skin is still hard, delicate, and impractical.

Sex doll upgrade
By the end of the 1990s, the bone performance, skin feel and facial features of sex dolls had been significantly improved.
Japan has begun to experiment with artificial bones to make dolls, hoping to give users a more realistic feeling with more flexible and changeable postures. However, the structure of human bones and joints is complex, flexible in movement and difficult to imitate.
In addition, people have also begun to use silicone or PVC materials with advanced medical non-toxic software to make sex dolls. These materials make contact more flexible. People put batteries on the dolls to immerse them in a real hug and keep them at a constant "body temperature" of 37°C for a period of time!

At first glance, it is difficult to tell the difference from a real person.
In terms of appearance, the appearance of sex dolls has also made a qualitative leap. Their hair is made entirely of real materials, and most of their faces are made by porn stars.
The future development of sex dolls
"Further improvement of simulation" should be the mainstream trend of the future development of sex dolls. Now, sex dolls can simulate the gasping, body temperature and even the release of body fluids of real people! In the future, sex dolls may be able to recognize users, flirt with users, play sex games, and react differently to users' different postures and positions. Now many people choose full-size sex dolls and want the best sex state.
