Without prior discussion have you ever surprised your Dom/me with something you thought they might like but weren't too sure? For example, a journal about your day, fetish clothing (even though you weren't entirely sure about the reaction), toys...

Is initiating things too much like topping for you? Has your Master/Mistress ever been displeased or unenthused by your gesture? Did it completely fall flat? Was there some sense of humor about it? Annoyance? Consequences?

Or do you always make sure to ask first?
