We have had several threads on different forms of orgasm control and conditioning techniques used to achieve this very result.

In some cases (such as my own) one can even be conditioned to cum on command, sustain orgasm, and even stop mid-orgasm involuntaraly with the proper "trigger" and all from a cold stop with no prior stimulation.

As for those that dis-believe all I can say is you apparently have as yet to meet a dominant skilled in such things or he has decided not to use them with you.

In any event it is certianly a word view blowing epiphany when you realize that such control can and is being used over one's self and not something to be entered into lightly.
