This might sound weird, but I'm going to say it anyway

. My boyfriend choked me once during sex, and compressed my carotids. The choking wasn't out of the norm but he was particularly rough and high up on my neck that time. I started to lose consciousness quickly- my vision went dark and my head felt full, hearing went muffled, I don't remember having trouble breathing, and I felt a pull into nothingness if that makes sense. I honestly was hoping he'd kill me, despite this wish being fucked up and unrealistic. All that to say, I think if I could do that to myself through partial hanging, it would be a nice way to ctb.
