I remember reading a story of a woman going to her end with her hands bound in front and a crotchrope pulled tight backwards from hands to neck - also a very erotic idea - and hanged with a short rope so that she'd be slowly strangled rather than a quick snapping of the neck. The story was good, the thing I recall the most is this line:
I tried really hard to look sexy as I hanged, but I had other things on my mind.
