I love breathe play - but only with a Dom I really, really trust. When my Dom and I first started experimenting with breathe play, we didn't do hand / arm bondage at the same time, so I could easily have stopped the play if I needed to.

I do like the sensation of being choked a lot, but my Dom thinks its better to put his hand over my nose and mouth - and so usually we do that. I find that it is a different sensation for me - but both create a 'seeing stars' and euphoric sensation (similar to if you have ever been given nitrous), and both have a control aspect that I love.
