Well, just to update, I haven't needed a safeword lately, but if he's worried about me he'll ask what color, and I'm generally green. Once I was at yellow. I have not used red yet. I have been unable to give a color at all occasionally in subspace and then he just backs off me anyway. This was also his question at the last munch, and the presenter recommended for him to find ways to take me deeper or bring me out of subspace at his will, as well as having me hold something that could be dropped as a signal, which is easier than talking I guess. I like being in subspace, and would just as soon stay there for a while
