Page "Sex doll" Paragraph 15

CybOrgasMatrix dolls used an innovative material — a very elastic gel with a strong shape memory, which they have shown in side-by-side tests is superior to silicone in elasticity, shape memory, and durability.

Additional options listed on the company's website at one time included a pelvic thruster motor and audio capability ( using wireless headphones ).

Similarly, the First Androids company once offered a wide range of options to enhance the realism of its dolls, including heated orifices.

Several modern doll manufacturers now offer this option on their silicone dolls, with the addition of an internal heating system.
