Please excuse my curiousity, but I've gotta know. Is it really possible for a submissive to be "trained" to the point that he/she will come upon demand. I understand how one could be trained not to come until given permission, but can the mind really reach the point that mere permission, without physical stimulation, will cause an orgasm? As you can probably tell, I lead a vanilla lifestyle, but I'm really intrigued by the dom/sub relationship.
