First Crucifixion

Pouring through all of the stuff here has really gotten to me. My boyfriend and I are going to try my first crucifixion this weekend. We have access to an old barn, so the beams in place already form a good cross, I think. I am going to be fastened with leather cuffs as neither of us really know the proper way to fasten me with ropes and leather cuffs should lessen the chance of damage to me a great deal. And I'm sure there will be some whipping involved as well.
My question is how long...
