Subs ALWAYS have the right to say no. As has been said many times on this site, just because you are submissive does NOT mean you are a doormat - some kind of stupid person who is expected to do as she/he is told because a Dom/me says it should be so. However, I do understand that limits (soft or hard) can change. Just as your relationship with your Dom/me changes - trust builds, a special relationship forms and in many cases, limits, which at the outset are set in stone, appear less so, until you find that you are happy to dip your toe in the water - more for yourself really than your Dom/me as it shows you just how far you have come, and WANT to do for your partner. This is what I have found anyway. But never have I been browbeaten into doing anything that I wasn't totally comfortable with so in that respect I am lucky. If a Dom/me could not accept that my answer was no to something, especially something that had already been discussed as a limit for me, then I'm not sure I would be able to continue in his/her service as, without basic respect between dom and sub you have no basis for a relationship anyway. Of course I am very new to all this, I have had one Master online and now have a r/l Master whom I trust implicitly so my knowledge is limited, however just from reading the many postings and blogs on this site has shown me that a sub is very far from a weak person and should something be asked of you which you consider to be unacceptable hold your ground - with proper discussion between the two parties things may become different but hold your ground if you aren't comfortable, you owe that to yourself.
