There is no wrong way,, No set way of doing 'it'.. BDSM is completely subjective.. Explore who you are in a safe, sane and consentual manner.. And never cross any boundary or comprimise any of your morals.. Don't do anything you do not want to, either conscious consent or consentual non-consent (like when your being raped but your body is loving that your mind cant stand whats happening..)
It is something you know about yourself, obviously.. Try to harness that raw pleasure you feel when you think about these things and make them come to life..
This is something that goes with with you for the rest of your life; it grows..
