I LOVE IT. I beg him to do it to me. Favorite tool to choke is the belt
I like the force and power trade of light choking but not with an item, only with his hands. I have a "hand kink" and love to see, feel and touch hands so I think it's more about that then about the feeling of being choked. I really freak if I can't breathe freely.
This isn't something we've tried. It's come up in conversation (general discussion) but neither of us is especially interested to give or receive at this point. If we do give it a try, I think it will be along the lines of some pressure - power play rather than actually cutting off air supply.
He's only ever put a hand over my mouth during sex once (I was being too loud for the place we were at but him covering my mouth only turned me on more!). I have been playing with the idea of choking but only with hands. However I don't think he'd be comfortable with it at all.
