Not really understanding the doorknob hanging and how it works. Tie the rope to one doorknob, throw it over the door, go around the door, and what? A noose that tightens? Are you standing up or on the floor? Why couldn’t you just get up when you can’t breathe? Or open the door (assuming you had slammed it upon deciding to go). I’m not much into physics.
Also. The auto erotic thing. Sam thing, why couldn’t you save yourself? And have women EVER been into this? How good could it even be?
RIP to this woman and prayers for her loved ones.
What happens is that enough pressure is put on the carotid arteries to cause semi-consciousness - that's the point auto-erotic fetishists are looking for - and when the body slumps the person is unconscious as the noose tightens to the point of lethality. They don't wake up choking because they can't. I was once acquainted with a seemingly normal guy who died that way and somebody had to tell the parents. Not a job I'd want.
