Inanimate fetishes come in three varieties - animate, media and form. Media fetishes include latex, rubber, leather and silk. With a form fetish, it's the shape of the object with great significance. Knee-high boots and lingerie fall into this category. Such body parts as feet, hair, butts, breasts, and all that good stuff are also considered fetishes, but as these objects are human, they are called animate fetishes. People can turn anything into a fetish. There are different degrees of fetishism - from mild to extreme bondage. Bondage and fetish are inseparable notions.
