Murder/manslaughter is murder/manslaughter.
Of COURSE you shouldn't be indulging in any kind of kink/bdsm play without first discussing it, making sure there are safe words/signs, knowing the risks.
But please, ffs, if it doesn't appeal to you, or doesn't get you off, then fine, but stop kink shaming other people.
As long as they're careful, what consenting adults do with each other in the bedroom is no-one elses business.
you DO absolutely 100% need to trust your partner, you never ever go whole hog into this kind of play, you introduce it slowly and test it out to see how you both react and its vital you stop when they say stop.
Never, ever, EVER do this with someone you cannot implicitly trust.
