I have a safe word I can use with WB, though I have not had to use it yet. When our play started to get more serious, I just thought it good to have one, even if just to alert him very quickly if something is going on he is not aware of.

We do not play in chat, but use Skype, so he can hear me and see me via my webcam. Still there are times our play causes a lot of emotions for me, and it is good to know that if I need, I can call a stop to things with one word.

That does not mean I do not trust him to notice what is going on too, but as Oz says I am also responsible for telling him how I am doing. Having one word, I can use to quickly alert him to any major change, just seemed like a smart option.
