Probably not enough pressure. Can you explain how did you do it?
I tightened the ratchet strap as much as I physically could, and it wasn't enough, apparently.
I got a rope and made slipknots on both ends, put one on the roof, and experimented with different heights. I first tried to do it while sitting, but I couldn't get it to work. Then I stood up and tried squatting (like I saw in pictures of scenes of suicide). It just creates a horrible sensation in my head. I tried to do it quickly, because that's what was advised in the books I've read, but it didn't work.
Just read the last 10 or so pages of the hanging mega thread. If you're gonna succeed then the advise will be there but unfortunately this is a brutally difficult method to get right and many like myself have mostly given up on it.
I don't understand. I've read about how people ACCIDENTALLY passed out. For fuck's sake, a lot of people die from auto-erotic asphyxiation accidentally. I don't get why it's so difficult. :(
But thanks, I'll read the last pages of the megathread.
