What does NO mean to you?

[Polaris]

i think especially being a sub i do say no mostly to the things i don't want to admit i like or want that can make me feel embarrassed.. Or when i want to be a tease ...

Yup, same here. No in my case means mostly "omg, please don't make me admit that I actually like that *gasp*". I acknowledge that no dom can be a mind-reader, although they seem to have a sensor for when you messed up (gah!), so I try to not do the "no" or "stop" thing. Personally, I would expect somebody to stop when I say my safeword (of course!), and I voice it when I'm out of my comfort zone and close to hit a limit.

I think, however, that it's better to stop when you're not sure whether it's still okay and enjoyable or not, especially when you don't know your partner very well. Stopping a scene when it is not necessary certainly is frustrating, but it can also shed some light on misunderstandings that might be out there. And being frustrated is certainly a better feeling than having somebody walk over your limits, or not taking sufficient care of you.

Just my two cents, of course!
