An interesting concept. The crucifixion is cruel, but necessarily so?
You are right, of course. Crucifixion is a cruel and painful experience for the victim. I can only try to explain the apparent contradiction in terms of fantasy.
I'm not generally interested in the BDSM scene. don't get turned on by witnessing scenes of pain, suffering, cruelty or torment. If anything I'm usually repelled by them.
What triggers my crucifixation comes from one of the oldest, of male fantasies. For me it's not so much the victim's sufferings as the distressing predicament that the victims find themselves in. Lonely, isolated, friendless, helpless, despairing, appealing, humiliated, perhaps subjected to the jeers of a mocking crowd. Whenever I imagine such a scenario I start to salivate. It's a Pavlovian response.
What we have is a Damsel in Distress, and it's the aesthetically beautiful, and often intensely erotic poses struck by the struggling, naked victim that actually trigger in me a protective response. Imagine Botticelli's Venus, rising from the waves in chains. I can't take her clothes off but I could take away the chains.
Most Damsels in Distress require a rescuer, and in my dreams I can become a Perseus to an Andromeda, a St. George to a Princess imperiled by a Dragon, a Knight Errant to a Fair Damsel, or a Fearless Fred to a Hapless Heroine tied to a Railroad Track by a Dastardly Villain. Or for, that matter, become a saviour to a crucified victim.
Any further torments inflicted on the victim tend to be something of a turn off for me. They are, aesthetically, displeasing. So, no damaging disfigurations, maulings or mutilations, burnings or breaking of bones, no floggings or flayings, cutting or cruel cornus (although uncruel ones are cool).
And of course, no arrows in the tum.
I daresay that if I turned up in one of your fantasies, Eulalia, you'd probably tell me to just eff off and go away. I might just pop back later, just to see if you were sure, maybe only to be told to "just piss off and get lost" once more.
But, hey ho, you can't please everyone. No doubt there will be plenty of other willing victims on the beech, so to speak...Happy fantasising.
