If i'm a sub then i'll do whatever the Dom want's that i'm in the scene with at the time. well, i'm not going to rob a bank or kill someone, so i guess i'll have to live with not being submissive. lol. i've had times where my limits and comfort levels chage and my Dom/Top at the time always is watching and communicating.
Among my friends, and i'm sure other people out there, no means no. If you have something that you don't feel comfty with doing, then no is always there in this case.
btw i thought it was slaves that couldn't ever say no,and that was after they were trained, collared,ect. . .But that's a whole different beast/topic.
