Sex doll or blow up dolls are a type of adult sex toy that aim at mimicking a sexual partner for use during masturbation. The blow up doll often consists of a body in its entirety including the face and body, or in some cases is limited to an off cut being either a region of the body which encompasses the vagina, anus, mouth or penis. Some sex dolls (known also as love dolls) have vibrating or interchangeable parts increasing the variety of stimulation. However, all sex dolls have one primary purpose...sexual stimulation.
