i don't got time for this

PSA: Please teach your partner how to choke properly if you’re into that kind of thing.

The point of choking is not to crush the oesophagus, but rather to put light pressure on the carotid arteries to stop oxygen circulation to the brain. So tops, please create a V shape with your hands, which allows the fleshy part of the palm to rest against the oesophagus without causing any obstruction to the windpipe, and press down on the arteries. It’s not about stopping your bottom from breathing completely, but making them lightheaded.

This is very, very important!

Also, please don’t attempt any choking whilst under the influence because your better judgement may be impaired and you can cause some serious damage.

There is no fully safe way to do this, there is always a risk of death. Sudden, unexpected death. Educate yourself about it before deciding you want to take that risk.

I suggest starting here:

Written by someone who is both a BDSM practitioner and an expert legal witness on the subject who knows his shit.

Read the whole thing several times (confronting a wall of text is the least you can do if you’re going to be trying breath play, it is not an inconvenience, it is a requirement that you educate yourself). Get your partner to do the same. You need to understand that these risks and consequences are very real. That link covers the dangers, and what will happen, legally, if you kill someone during a scene. (They will be dead and your life will be effectively over, and you will forever shatter the lives of their loved ones and probably your own loved ones.)

The core of the safety issue regarding breath play is that, unlike almost all other forms of BDSM play, breath play doesn’t go “just a little bit” wrong. If the unexpected happens, we’re not talking about causing a bruise, welt, laceration, or a burn. We’re talking about causing the complete destruction of a human life and, so to speak, choking off everything that person might have done with their life had they not been killed. Further, we’re talking about killing someone in an utterly legally inexcusable way…. If the worst happens, then one life is over medically, another life is over legally, and all the people who loved and cared for both of those lives are heavily damaged…. The pseudonymous people who try to convince others, at no risk to themselves, that breath control play can be done with reasonable safety are absolutely correct, right up until that medically unpredictable, legally indefensible, life-destroying catastrophic moment when they couldn’t possibly be more wrong.

Tumblr is not the place to get your education on this. OP is wrong. Yes, you can do this, you can do it for fun and it can be fun, but it cannot be done safely. At all.

For adults, the appeal is Sir Patrick Stewart doing a kid’s educational bit in full Shakespearean dress and style; there’s a delightful cognitive dissonance between the very serious presentation and the very simple content.

For very small children, it’s educational: this is the letter “B”; here’s how it’s shaped; here’s some words you know that start with it. Oh, and here’s a word you may not be familiar with that starts with it, so you can recognize that it’s the sound that matters, and not whatever other connection you made between the other two words.

For older kids: you’ve probably heard that “to be or not to be?” speech, or at least part of it, so you can enjoy some of the parody the adults are watching. Also, here’s how to describe how a letter is made - how to teach young siblings who don’t read yet, how to explain both the shape and the sound.

For kids with dyslexia: here’s how you differentiate a “B” from a P or D or E. You may have to go slowly and look carefully at the exact shapes that make up the whole, but there are differences and you can learn to recognize them. 

For teens or young college students: In addition to whichever parts of those are relevant to you, here’s what Shakespearean acting sounds like. Here’s how to enunciate clearly and slowly, so your audience can understand terms they may not recognize and still follow the gist of what you’re saying. If you’re reading Shakespeare in school, try sounding it out like this and see if that helps it make sense.
