I was never into breathe play, but it recently came up in with a friend. Its a hard limit for me. I would never do it or have it done to me. Too dangerous for my liking.
I went through first aid/cpr training for my work. It would be a good idea for both people to go through it just in case. Classes around here are usually 6hrs and cost $50-$75. Worth it in case something goes wrong. I know I would feel better about having it done to me if the person had the know how to save my life if needed.
