Well, Bill, for several yrs ---too young to talk about here---I was 'owned' and 'trained' by my master/mentor, who himself was trained in Eastern disciplines from early age. We could be at an opera and he could lean over---w/o touching me in any way, and whisper "Come for me now" There's no way that I could have resisted, had it ever even occurred to me.
I was privileged to learn how to pleasure every inch of a man. And I was serious about 'cocksucking 101', were I the instructor being able to make precum drip in a stream, focusing on the knob and with the tip never passing as far as the teeth would be absolute minimum to progress farther. So many people know so little about their own bodies, let alone their partners......
