It also can retain warmth, so if you decide to heat it up a little bit, it definitely has that potential. However, you shouldn’t try to give it hot baths or submerge it too much, since often, this can mess with the skin, breaking it down and ruining the doll. But, if you want to mimic the warmth of a body, then you can use this, since often the fact that it is way more sensitive does help with this.


Also, be careful about bacteria. The problem with TPE is that it’s super porous. That means that the bacteria on your hands and such can get into the skin. Not only that, the orifices are typically prone to absorbing the bacteria from semen and other such excretions. It is important to realize that since it is porous, it means that you have to clean this up excessively each time. You can’t let this sit after you’re done with it, because the moisture from this will be left in the cavities, and from there, it can grow mold, and that often is pretty gross. That means that if you’re going to get a TPE doll, don’t let it sit with any sort of moisture inside of it, because let’s face it, you don’t want a moldy doll. This also might not be the doll for you if you’re not the type that is okay with doing a tiny bit of cleanup after sex, since often that is what is required, and it is something that you will need to consider.
Better Performance - Sex dolls are excellent partners to help improve your technique in bed. By masturbating with a sex doll, you are able to practice how you thrust, breathe, and pace yourself for a longer session. You can in turn use the opportunity to figure out how to best stimulate the clitoris from various angles and get the deepest penetration possible, without ever having to deal with an exhausted or annoyed human companion.
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]
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.
