You certainly are not the only one on the planet to have an interest in this.
But I wonder why there are so many who are fascinated by the thought of being crucified. It's not as if it is a pleasant idea.
Could it be the thought of being subjected to such agony? Well any form of torture would suffice.
Could it be the notion of sharing the same suffering of Christ? One would have to be deeply religious to take that on board, but it is the reason why so many saints & holy figures have earnestly desired to empathise with their crucified Lord. Well that is what they admitted to, but just maybe there was more to it than what they admitted to? A desire that goes beyond piety, one that we understand & freely admit to here!
Is it the desire to be manipulated into a horrible experience against one's will? The 'I am the innocent victim' syndrome?
Could it be the fact that as a crucified victim one is the centre of attention of a lot of people? I'm sure there is something in this. As a very shy person being the centre of attention in that way is something I would dread, that makes the whole thing a fascinating nightmare for me!
Lastly could it be the sexual element of being publicly exposed to a crowd of people totally naked? There must be a lot in this, if not everything for us here. Not so much the exhibitionist thing of the flasher male, but more the shame of one's intimacy being put up for everyone to see, though I am sure there is a bit of the exhibitionist in it. The crucifixion pose is a really erotic way for a body to be exhibited, it shows everything starkly; breasts pulled up, belly & chest stretched, arms wide & in supplication, genitals in full view, etc.
But there is also the ritual involved that I think is fascinating & appealing to those interested in trying out the victim bit. There is a narrative that goes from mockery, violence - beatings up, stripping, sexual mistreatment & scourging. Carrying a heavy beam through crowded streets. And finally nailing to a cross & being raised up for all to see till one expires hours or days later. It's a narrative far more evocative than any other execution method.
