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. 
Sex dolls, also called blow-up dolls, are male sex toys that offer the sensation of penetrating a live partner. Nearly life-size, these sex dolls have openings in all the traditional places: mouth, vagina, and anus, so you can penetrate every orifice to your heart’s content. Some models are even equipped with large egg vibrators to increase stimulation and maximize your orgasms.
The final thing, is that it is also hypoallergenic, and that means that you won’t’ get allergic to it. With some people, they are unfortunately allergic to silicone, which can be a problem over time. You might want to consider this if you know that you have a silicone allergy and you still want a sex doll, since it can help alleviate this problem if you do have it.
Also, some argue that while it is more realistic to the touch, it might not be to the feel. Because of the fact that the TPE skin is much softer, sometimes the heads feel a little bit different. It might feel softer to the touch, and you might almost feel a bit weird since you can sometimes press the head in. This might be something to consider if you’re worried about potentially ruining the reality of the situation because of the way the doll feels.
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.
