But those acts are already illegal.
It's illegal to choke someone or beat them.
It's just saying that those acts don't become legal simply because it's sex.
Yes, yes, but then (perversely because it makes no logical sense whatsoever) it would appear that according to the CPS/juries/British judicial "actually, yes they do become magically legal in a heterosexual context when a woman is the victim." See for example the recent case where a man was put on trial for manslaughter rather than murder having stabbed a woman he'd only recently met and was having sex with for the first time, because he was into blood play, kept a knife under his pillow (as you do - nb sarcasm alert for those struggling with tone on the internet) for just this eventuality, and left her to bleed to death. He said it was consensual ("Well, he would say that, wouldn't he?") she was dead so had no input into confirming or denying this, and the bastard effectively got away with it.
And this is only one case of many. There are countless women who've been choked to death during sex, but this is apparently sex gone wrong and therefore manslaughter rather than murder. There are women out there who've been beaten black and blue during the course of rape, only to have it passed off as "rough sex", so no rape conviction.
I have completely had it up to here with the "your kink is not my kink and that's okay" shite. Some kinks are very much not okay. Some kinks are about woman hating, rape and murder and they are really, really harmful - not just to individual women when they "go wrong" (otherwise known as the man actually enacting the fantasy he's harboured all along and committing rape or rape-followed-by-murder quite deliberately, knowing society will let him get away with it because apparently "kink shaming" is a worse crime than rape and murder), but to all women - because we all have to live in this shitty, fucked-up rape-and-murder culture.
If I come across as angry about this, it's because I am angry about this. And if you are not angry about men getting away with rape and murder using the "rough sex" defence, then there's something badly wrong with you.
