I think you've misunderstood my post, which is to point out that no, most people aren't strangling each other during sex, and one of the reasons people think they are is because there are other sexual practices that some people mistakenly believe are strangulation because they get called 'choking' - which in most cases isn't what is actually happening.
Some people like their neck being touched. Having your neck touched with no pressure applied at all doesn't 'easily go wrong'. It's just a hand resting there, not pressing or squeezing. Simply touching someone's neck is not something that accidentally cuts off an air supply, much like holding someone's hand as you walk down the street with them isn't something that can accidentally break their fingers, or giving your boyfriend a playful pat on the bum isn't something that can accidentally leave a bruise.
Applying pressure to someone's neck absolutely does easily go wrong and nobody should be doing that in bed, ever. To even come close to cutting off someone's air supply, you'd definitely have to be very, very deliberately applying pressure in the first place, which is what was supposed to be happening in the Coronation Street storyline - and what happens in the horrific cases where the 'rough sex defence' (which, of course, shouldn't even be a defence in the first place because it's utterly fucking grotesque) is put forward in court. It's not at all easy to strangle someone by accident - lots of people aren't even physically strong enough to do it. When someone dies like this, it's because their partner was actively trying to restrict their airway for sexual purposes. That is what can very easily go wrong.
Most people aren't doing that, thank god. But I still think it's very important for people to know that it's an appallingly dangerous thing to do and that anyone who actively wants to risk doing that to their partner is almost certainly a complete fucking headcase who belongs in prison.
