Do you have a theory about why people are willing to risk their lives to get off using auto-erotic asphyxiation?

I like sex as much as anyone, but this practice really creeps me out. Given all the stories about how you can die doing it, I can’t imagine why anyone would try it at all, much less try it alone. What kind of frame of mind would you need to be in to want this supposed high? To be willing to die for an orgasm… I just don’t get it. Is there anyone who can explain?
