PSA #1
Safer forms of breathplay exist than strangulation
If you like the feeling of asphyxiation, you can simply hold your breath. You could put bondage tape over your mouth, hold a cat bell to ring, and have him hold your nose if it's that fucking important to you that he controls your breathing. It's still risky because he might not let go of your nose, but it's less risky than him crushing your throat.
Him squeezing your neck can fracture the cartilaginous structures, like the larynx. It puts pressure on the veins and arteries in your neck, which can cause strokes and brain death because the blood pressure in the brain goes too high, rupturing blood vessels, or too low, starving the brain of oxygen.
If you cannot orgasm without being put at proven risk of death and brain injury, you need therapy. If he cannot orgasm without putting someone else at risk of that, he needs to be in prison to protect all women from him.
PSA #2
Kinkplay without a safesignal and limits set is inherently dangerous and abusive.
I bet all these posters saying that their husbands strangle them, by request or otherwise, have never had their husband ask "what's your safesignal?" I bet they've never been asked to discuss preferences and limits. They've never had a cat bell tied to one finger to ring if they want to stop.
When I was on "the scene" twenty years ago, the test for doing something at all was that it had to be all of "safe, sane, and consensual". Strangulation is never safe and never sane. There is no excuse for it, ever.
