Anal, spanking and bondage, within a consensual, mutually respectful relationship isn't what was being discussed, though, @Batgin. Strangulation is so dangerous - doing it wrongly, just once, can result in death, or can cause the person to have a stroke days or even weeks later, due to trauma to the carotid arteries. I cannot see any benefits that would outweigh those concerns - and I used to be active in the BDSM community, so I am no stranger to kinks, safe words etc.
Plus, if what I have heard is right, some young men are seeing choking as part of rough sex videos, and are going ahead and choking their sexual partners without any discussion or safe words, or are pressuring young women into choking as part of sex - in my experience of the BDSM community, communication and consent were absolutely key to any kinks, and pressuring people into going along with kinky sex, rough sex, violent sex, choking etc, was an absolute No No.
The problem is the proliferation of rough/violent porn, and the ease with which young men are finding it, and learning from it. You can't learn respectful, caring, mutually satisfying sex from a rough sex porn video - all you can learn is how to treat your sexual partners like shit - and no-one should be advocating that.
