any tips on a proper choking?

Autumn • Ashes

so I really like being choked, but... is it too hard when you can't breath at all, and your starting to inhale saliva?... Because my man pushes his thumb into my windpipe, and it's just no.. I never tell him to stop because I somewhat enjoy it, so can I just here some tips on what it should look/feel like?.. other than that I love the hair pulling, pushing, clawing, etc! 😍
