In a different thread the topic of choking during sex has come up repeatedly. Some women say they enjoy it and it's none of anyone else's business. Others have said it gives abusive men an excuse to hide behind if and when they murder their partners- see here for some tragic stories but bear in mind they're upsetting https://wecantconsenttothis.uk/
My own point of view is that choking during sex is dangerous. Study after study have pointed out that it can cause death or lead to brain damage. It's easy to find this information online but here's an article about it https://www.webmd.com/sex/what-is-sexual-asphyxiation I do think people should be able to do what they want sexually if it isn't hurting anyone. But I also think people should be aware of the risks. In the other thread people who raised any objection to choking during sex were called "pearl clutchers" or "sex police." AIBU to think no, knock yourself out if that's what you want to do but at least acknowledge it isn't a safe sexual activity?
