Still really dangerous which is precisely why you need trust, a safe word and/or gesture, and extremely good communication with a partner you're doing that with. My ex abused me and was into strangulation. Before him, I liked it too but he would escalate more and more, disrespect obvious signs of panic in my body, and use it as a way to keep my body submissive even when "kinky stuff" or actual sex wasn't consented to. The entire relationship really shattered my trust in people and ruined confidence in my ability to keep myself safe in that kind of situation. I've been with an excellent, kind, and trustworthy partner for two years and I can barely trust in the most vanilla of kinks. I feel like it has ruined lots of things I used to enjoy before the ex irreparably. My advice? The key to kink is complete explicit prior consent to a scenario and absolute trust. I no longer have any tolerance for hands on my face or neck. Sometimes, even clothing which is too tight or falls wrong on my neck gives me flashbacks. It makes it worse knowing that to this day he still doesn't understand why it would be a problem to strangle me improperly until I started to black out or to have sex with me while I was asleep or why holding me down with a hand over my mouth so I couldn't talk or move and therefore couldn't try to stop what was happening was fucked up. There was extensive emotional abuse and he systematically isolated me from every friend and family member I had. Now he tells everyone that I abused him which would be funny to me if he hadn't absolutely ruined my life over the course of four and a half years. I was into kinky stuff, had consented before, and therefore asked for the sexual abuse in his eyes. I'm still working on being able to fully enjoy my kinks at some point in the future, to love my body, and to be confident in my sexuality again. Kinky strangulation is also dangerous and when it goes too far it is absolutely terrifying. Abusers will always find a way to use the trust you place in them against you.
