Well said denuseri. Communication is always important, especially in an area such as this. Since everyone is different, humiliation works differently with each of us. For me, there are certain things that are on my hard limit list because of past abuse(not in this l/s). i am very upfront about it so my Sir/Master is aware of course. Some like being slapped in the face or spit upon and get turned on by this type of humiliation. Not me. Slapping my face would most get a reaction like cowering and/or bursting into terrified tears. Anyway...
my Sir has pushed me hard as far as humiliation goes. i am shy and very private as well as a big chicken so this can and is very hard for me at times. He is much more into it than i am,lol. It's a turn on to a degree but not like a nice thick belt across my fanny!
i have had tasks like flashing on the highway, driving on the main highway with my shirt gaping open for 100 miles, alot of what He calls simple. But to me, it takes me awhile to get the nerve up.
Safety is always both of our concern as is people in public, family, co workers...stuff like that. As denuseri said, comfort and being turned on are 2 things to consider as well.
