You tell him what turns you on... most escorts have heard of, seen, and done it all. It's not like your going into the confessional and the priest on the other side of the screen would have no idea... but then agsin that might not be the best example to use...
BTW, the first time I experienced ice was when with an escort... I was not quite sure why he had gone into the kitchen, but it was soon evident why.
Also, works great in combination with hot wax... for that fire and ice effect with both TT and CBT!
