When I my girlfriend hinted that she liked to be bound about six months ago I wondered how far she really wanted to go. I have asked her about boundaries but she just says “you haven’t hit it yet”. We do have a “stop” word that she has yet to use and I advance carefully and slowly to new forms of discipline. I know this is a personal preference to many subs but I would like to hear some opinions from sub and dom’s as to how far is too far.
