I'm not really old, I'm 37.
What I find pathetic are the some WOMEN acting all cool and mighty: oh look at me, I'm so unique, cool and edgy, I luuuv me some 'breath play' (how can you feel cool and edgy using kindergarten terms, beats me), being fucked in the ass, slapped, spat at, bound up, being pissed on, yada yada, it's so liberating, sexy and safe, I enjoy it so much. With the undercurrent of 'I'm so fucking progressive, not like you, you old, boring, pearl clutching hags, whom no one wants anyway'
Enjoy it, I personally don't give a fuck, really. If your 'kind and loving partner you absolutely trust' accidentally chokes you to death one day, I'm sure he'll cry and be sorry, you'll be nice and dead and he'll continue his kind and loving life. But you chose this, so whatever, I can't muster any fucks to give.
What is not ok, is this shit being pushed as normal, 16 year old twits choking their timid 16 year old girlfriends who don't like it at all, and don't want it, but are afraid to say no, because 'everyone enjoys breath play' apparently. Except for frigid, boring grannies. And who wants to be a frigid, boring granny at 16.
And as for 'reasearched and safe', I remember being 16. Some of my similar aged boyfriends didn't know what a clit is and how to find it, and/or were gobsmacked that an actual girl has hair on her fanny or legs, because mags and porn showed them the shaved ones. I can imagine these boys sitting and studiously reading about safe strangulation, yep. Put your hands on the neck and squeeze, more like.
Or adult women, timid, shy, without much spine, people pleasers. Who won't say no for various reasons. And might end up dead or brain damaged as a result.
Pissing into each others mouths won't kill you. So whatever, some people claim to like it, and it shouldn't be made illegal. Choking kills. So that should be a crime.
