A sex doll (also love doll or blow up doll) is a type of sex toy in the size and shape of a sexual partner for aid in masturbation. The sex doll may consist of an entire body with face, or just a head, pelvis or other partial body, with the accessories (vagina, anus, mouth, penis) for sexual stimulation. The parts are sometimes vibrating and may be removable or interchangeable.

The most premium sex dolls are usually made from silicone or thermoplastic elastomer known as TPE. 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.
* TPE dolls which includes: realistic sex dolls which are adult sex dolls purposely designed to better replicates a real  woman in her natural movements and feel with skin texture that faithfully replicated the realism of human skin; classic TPE dolls that are conceived according to well established and proven methods design and manufacturing techniques and finally the heating and moaning love dolls that support interactive functions that mimic the experience of love making with a woman
Cheaper sex dolls are inflatable, using air. These dolls, representing the lowest price-range (less than US $75), are usually made of welded vinyl and bear only a passing resemblance to actual people. They have an artificial and typically crudely designed vagina or penis, but due to their affordability many users are willing to overlook their shortcomings. They often burst at the seams after a few uses, although they are commonly given as gag gifts and therefore many may not be used at all. In Russia for some years the Bubble Baba Challenge humorously featured participants river rafting on blowup dolls as a matter of entertainment but in 2013 the race was cancelled on "health and safety" grounds.[10]
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.
