BDSM :(Bondage, Discipline,Sadism & Masochism) The Religious and Spiritual Perspective

The paper is dealing with the non-sexual side of BDSM and how most people only view the sex side due to mis-information. I would like this paper to go from the past BDSM practices to current.

I am looking to have information from multiple sources including the internet about Shia Muslims marking the holy day of Ashura with self flaggulation. Another, example to use is the ritual flaggulations used in a ceremony during the 9th century in ancient Sparta where the priestess of the Cult of Orthia oversaw the whipping of young adolecent men. Also, include the practice of pilgrims climbing using only their knees The Santa Scala, or Holy Stairs brought from Jerusalem to Rome in the 4th century.
To more of a modern era about the iconic BDSM pin-up girl of the 1950′s and 60′s Betty Page to finish out the time-table.
