There are various studies by the psych and the med doctors, because, allegedly, young people have learned and copied strangling as a form of erotic play and they are doing this even in vanilla sex.

Anyway, vanilla sex with strangling might kill some but I do not know if we have any numbers. Bdsm with strangling has resulted in 15 deaths reported enough to be included in the study published in medical literature.

As for deaths due to sex due to the exertion from either sex itself or from running or being a police officer who confronts irritating, aggressive criminals, I do not think we know the numbers! Oh, to the extent that we know the numbers, they are more numerous than deaths from bdsm . . . but then, bdsm is less common than vanilla sex, so . . . !

If you exclude strangling people or hanging them from a rope, which account for nearly all the bdsm deaths . . . then, anything and everything can kill you: bdsm, running and vanilla sex.

The case of bdsm leading to manslaughter charge in Massachusetts 10 or 20 years ago . . . was apparently due to a heart attack from stress!
