I strangle myself for pleasure. I have a nice black wrought iron bed to which I bind my hands and ankles so that I am spread eagle on my stomach, nude and helpless. I have a noose that hangs before me that I can put my neck in when I'm ready and a vibrator on the bed below me that will pleasure me when I allow myself that privilege.I struggle against my bindings and fantasize about being abducted and bound and abused, fucked, sucked, forced to do things I would never do, all the while being strangled, hanged, bagged, or asphyxiated. The imagination is a truly incredible thing...I can actually get myself worked into a frenzy from the images in my mind, and before I know it, I'm wet. I tease myself, lowering my cunt onto the vibrator, then lifting it up, struggling against my bindings, holding my breath.
When I'm ready, I slip my head through the noose and lay forward on the bed, feeling my pussy tingle. This is why I strangle, this is the attraction of asphyxiation and breath play to me - that tingle, the wetness that follows, and the insane orgasms that come later. Like the vibrator, I tease myself with the noose too, bringing myself to the edge and back over and over. It's difficult to describe the sensations.
When I'm ready, I slam my cunt down on the vibrator and imagine that I'm being brutalized. My neck in the noose, I imagine that my attacker is also strangling me from behind. My back arches, the vibrator plunges deeper inside me, and my vision starts to sparkle at the edges. The intense pleasure that ripples through my body is indescribable. Despite his best intentions, my orgasms with my husband (who doesn't know about my fetishes/obssessions) are nothing compared to the ones I get when I'm masturbating this way.
I wish I could share it with him. If nothing else, it'd probably be a lot safer than doing it solo. I know the risks and the dangers of doing it alone...but it's addictive. I almost strangled when I was a kid and for some reason became fascinated with hanging and strangling after that - in my teens, I tried to commit suicide by hanging a few times and ended up getting turned on by my body's response to the hanging. 
The scenarios I imagine are mindblowing - rape, gangbang, sodomy - bondage indoors, bondage outdoors, in cars, ON cars, on the ground, suspended in the air. You name it. These things even go through my mind when I'm fucking my husband. I find myself holding my breath...gasping for air...I'm not sure if he's noticed, and if so, if he realizes what I'm doing. I want so badly to ask him to tie me down and just do whatever he wants to me...and to strangle me...but I don't think he'd be into it.
Here's what turns me on. My back arched as tightly as it will arch, maybe arched over something - a stool, a log, the side of the bed. Hands on my waist, my ribcage, fondling my breasts. A tongue in my cunt and fingers tickling my clit. I've never given a blow job and find it kinda gross, but I've always fantasized about being throat fucked while I'm bound and helpless. My back and neck arched back while I'm fucking, the man's hands around me and behind my back, pulling on a rope around my throat, strangling the life out of me while he fucks me silly.
