I have to say from a Dom point of view ---That I have never felt let down by my subs use of a safeword----but my Idea in our relationship is for us both to enjoy what is happening to the fullest ----when it comes to the point that she uses our safe word ---all things stop ---no questions about it---
I know she trusts me but I am the one who insisted on the use of a safe word and since then we have a great relationship--It is more an understanding than anything beteen us ---there are times when what we do gets intense---and while I precieve she is enjoying something ---it may be getting just too intense for her---rather than turn something we are enjoying into something that she has stopped enjoying ---I personally would rather just stop at that point---
I would say talk it over with your Dom---you may be suprised that they really do not feel let down by your use of a safe word ---and it will make your experiences all the more satisfing----
the use of the safe word also helps your Dom set your limitations---so they know when to let up or stop the next time before you get to that point of having to use the safe word without that knowledge ---it is hard to know when to stop or let up ---
