It really depends on the level i guess, and whether the public actually sees. In my mind its not the public actually noticing that would get me going, but instead the risk involved. For example, if i had a toy in me in public, the thrill would be that i am in public with the toy/s in and Master having the controls to choose when it will effect me. I will try my hardest not to show what is going on, but thats the delight in it for me.
