The most expensive sex dolls (approximately $1,200 and up) are usually made from silicone (usually above $3,000 at 2016 prices) or thermoplastic elastomer known as TPE (below $3,000). Dolls made of either material can be very lifelike, with faces and bodies modeled on real people in some instances, with realistic skin material (similar to that used for movie special effects), and with realistic (or even real) hair. These dolls usually have an articulated PVC or metal skeleton with flexible joints that allows them to be positioned in a variety of positions for display and for sexual acts. Silicone or TPE dolls are much heavier than vinyl or latex inflatable ones (which consist mostly of air), but are roughly half the weight of a real human being of comparable size.
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.
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.
