Some of the first sex dolls were invented by Dutch sailors in the seventeenth century who would be isolated at sea during long voyages. These masturbatory dolls, referred to by the French as dame de voyage and by the Spanish as dama de viaje, were made of sewn cloth or old clothes and were a direct predecessor to today's sex dolls. The Dutch sold some of these dolls to Japanese people during the Rangaku period, and the term "Dutch wives" is still sometimes used in Japan to refer to sex dolls.[1][2]
TPE is the epitome of sex dolls if you’re going for one that feels good, and that is flexible. While maintenance is much broader in spectrum in terms of what you got to do, sometimes for those of us that do want to work to preserve our sex dolls, this is the one for you. TPE sex dolls are a great option if this is what you’re looking for, and you should definitely think long and hard on this before you do choose to spend money on one, since often, this can be a big factor in the decision you make. 
Now, TPE stands for thermoplastic elastomer, which is essentially a mixture of polyvinyl chloride and silicone. This is a type of skin that is very soft, and it mimics the feeling of human skin. TPE is way more realistic in feeling and it definitely mimics the feeling of human skin. It also is much cheaper than silicone alternatives, sometimes even hundreds of dollars cheaper. TPE also allows you to move the doll around in various ways, since it has more flexibility. TPE dolls don’t really need to be bathed, but you can, just be mindful of the water. It also is hypoallergenic as well.
