Sin

Is this a sin? I don't think so unless she does not consent to this sort of activity. On the contrary I would claim that she looks very beautiful in her confinement.
Who is to be the judge of what is sinful or not? I would say that any sexual activity between two (or more) consenting individuals ( human beings) is not a sin disregarding what is considered acceptable by society as such. Why this preoccupation with sex you might ask? Well, it seems as if sex is an inevitable issue when speaking of sin, but I might just as well be speaking of theft or murder. Is that a sin if you commit either one in order to survive? To quote D. H. Lawrence one can only sin against one's own Holy Ghost (genius). In other words: if you are true to that very core of what is you then you commit no sin whatsoever ( Do What Thou Wilt Shall Be The Whole of The Law).

How come so many people worry so much about the actions of themselves and others? Instead of watching upon each other ( and themselves ) in search of "dirty deeds" they should start getting a life of their own! It is so easy to apply your own values upon others but there is no guarantee that what is good for you is also good for others. We have here the basis of every prejudism, fascism, chauvinism and racism the world has ever known. I find it amusing (NOT!) that Christians are the first in line to condemn and persecute those who think or act differently. One clearly sees the true meaning of Christianity; it is not about love, tolerance or forgiveness: accept the heavenly authority and its dictations or you're an outcast doomed to burn in hell for all eternity! If that is love, what's wrong with S/M then?

To wrap this up I will state that anything that feels good and does not purposely harm anyone cannot be a sin! So listen up everybody: Cast off the chains that bind you, seek deeply within yourself. There is a flickering flame that needs to be kindled so that it may leave a burning mark on the skies for those who come after to remember you by. Life is among those who live!
