I believe it is possible for a submissive to reach an orgasm on demand with proper training. Please do not take this the wrong way, but it is known that in the food processing business animals are trained when to eat and when to sleep just by turning on and off the lights. It is also known that the same thing can be used to put fear in someones mind. Ring a bell and follow it with an electric shock. Eventually when the bell is rung fear follows. Apply this same principle to having sex or being stimulated and eventually it becomes a habit. For instance a certain sound or music could be followed by having sex...eventually...play the sound or song and U would become excited... Let me know what U think..
