Are you sure got the ice-fire treatment - or was it too early in the morning, and she hadn't finished brushing her teeth and rinsing her mouth??? LOL...
If this is distinct from the ice water/hot tea treatment - I have had mint strips in mouth treatment - nice feeling - probably not as drastic as the above.
Also an alcohol rinse is used sometimes prior to and after sex if you venture into the BBFS territory - now THAT will burn yah... but it is good for you...
Remember - what won't kill you - makes you stronger!
