Everyone has already said this but just to add my voice to the pile in summery:
1: I don't play even with my husband without safe words - I would cut off all contact with any Dom who tried to tell me I didn't need safe words.
2: As a sub I am the one who will be physically hurt when we play - therefore I have the responsibility and right to protect myself however I see fit. If I believe this is by having a safe word that is not NO or STOP this is my prerogative
3: As a Dom I would never discard safe words or use an easily misunderstood word such as stop because no matter how careful and how good at empathy you are you are NOT that sub, and you are NOT a mind reader - even being a sub sometimes myself doesn’t give me that privilege.
4: I don't use NO or STOP as safe words because Even if we are playing in a scene that doesn’t require the sub to 'pretend' non-consent people still have their own fantasies - I don't know if they secretly desire to be overpowered and 'forced' to submit - if this is the case they will say - stop you bastard, no don't do this etc.
5: things happen - cramp/ sudden realisation of the time/ remembering your mother-in-law etc etc you need a clear unequivocal signal that you need to halt all proceedings and get you untied/nipple clamps taken off/ corsets removed etc etc as quickly as possible.
I won't go into why the words STOP and NO are difficult for some if not many subs to use - if you understand it -great; if you don't - well just accept it - in all honesty the above reasons and examples of misunderstanding are enough to convince everyone that it is just 'safer' to use a word such as red or unicorn as a safe word.
