The only girl I've ever met who liked (or claimed to like) choking was a very unwell woman with severe self-loathing. She put herself in unsafe sexual situations all the time, essentially using it to self-harm. It's a fad with dangerous consequences, hard to talk about in polite conversations, and frequently used to conceal domestic abuse (I didn't strangle my wife, officer, she WANTED to be choked! It was an ACCIDENT that she died!!)
Pornography is getting so easy to access, so removed from reality, so intense, and so omnipresent, it's really becoming a problem. I don't want to sit here and say "well if porn didn't exist, Audrey wouldn't have shot up the school," but if Audrey hadn't had her mind rotted by porn and gooners online (who in turn were rotted by porn,) I feel like her life could've taken a very different path.
