I'm with icey here, bondage films and pro pictures are mostly not staged in anyone's kitchen or backyard - those places don't have the lighting conditions to make the bound body come out fine (if you shoot indoors without anything to help the photography it will often come out with obvious shadows clouding the model and so on - extra lamps and screens are needed to smoothen the light, blot out reflections and so on), and nor do they have space for a big camera and additional riggers etc.
