A sex doll (also, joy toy, love doll, fuck doll or blowup doll) is an anthropomorphic Sex Toy in the size and shape of a sexual partner. The sex doll may consist of an entire body, or just a head, pelvis, or other body part (vagina, anus, mouth, penis, breasts) intended for sexual stimulation. Sex dolls are made from various materials like silicone, TPE (thermoplastic elastomer), or rubber to replicate a lifelike feel. These materials are chosen for their durability and realistic texture, enhancing the overall experience for users. The parts sometimes vibrate and may be moveable and interchangeable. Sex dolls exist in many forms, but are usually distinguished from sex robots, which are anthropomorphic creations designed to be able to engage in more complex interactions.

Sex dolls first appear as consumer goods, sold in France beginning in the 1850s through rubber goods magazines as “rubber women” (femmes en caoutchouc).^{[1]: 115–116} These early sex dolls emerged from European and American industry during the 1800s Brazilian rubber boom, alongside the invention of vulcanized rubber.^{[1]: 117–118} The first documented appearance of these rubber sex dolls is in an article from French newspaper Le Figaro reporting from an exhibition of American rubber products at the 1855 world’s fair.^{[1]: 132–133} These goods were heavily criminalized, along with other sex toys produced in France at the time, and thus were produced and sold in small quantities at high cost.^{[1]: 124–126}
