Well, I guess this guy died because of some freaky things him and his sex partner did. Matter of fact, she's being taken to court for mansalughter because of it! But they were saying what might have happened was a pinched nerve which was caused by attempting 'auto-erotic asphyxiation.' That basically means oxygen to the brain is intentionally reduced to increase stimulation during sex.
What makes the story more interesting, though sort of a shame, is the man that died was once convicted of manslaughter from a similar act that he done to one of his past sex partners over 20 years ago.
You think I made this up? Nope. Go to The Chronicle Herald to read the actual story.
Again, I'm not trying to joke around too much about this. Just be cautious of your health and well-being when you have sex.
