I am not overly critical most of the time, but I do feel I should correct you on the descriptor you used for the picture since "sodomy" has nothing to do with this picture.
This would be more in line with a BDSM picture which has a few definitions. One being:
The term "BDSM" is an abbreviation derived from the terms bondage and discipline, domination and submission, and sadism and masochism, and describes a spectrum of behavior, usually sexual, which can include dominance and submission, punishment, masochism and bondage play, among other activities.
So this picture is more of the submission style of BDSM.
