I do not own any of these photographs unless otherwise stated. And the model's name in my sidebar picture is Tori Lane.
Body modification (or body alteration) is the deliberate altering of the human body for aesthetic or non-medical purpose, such as sexual enhancement, a rite of passage, denoting affiliation, trust and loyalty, religious reasons, shock value, and self-expression.
It can range from the socially acceptable decoration (e.g., pierced ears in many societies) to the religiously mandated (e.g., circumcision in a number of cultures), and everywhere in between. Body art is the modification of any part of the human body for spiritual, religious, artistic or aesthetic reasons.
