Anatomy atlases and medical articles are very useful. I leant a bit about pharynx/oesophagus ... o- It's very dangerous to use squirting dildos (or just ejaculate) while deep throating unless they go deeper than larynx. And this is deep and the you will not be able to breath because the cock or dildo will block the larynx.
o- You can't breath if the dildo is too thick (>25-30mm?)
o- You have to hold your breath and close larynx if someone/something going to ejaculate
Bottom line - if something come out of the thing in your throat, you can't breath, unless this thing is thin and long (>20cm?).
That answers a couple of questions I had regarding using deep throating in selfbondage.
