Are you talking about delaying orgasm while being stimulated? If so, maybe this will help?

I was just recently taught orgasm denial. The two "tricks" is use to delay orgasm are tightening my leg muscle(s) and thinking "no, wait". Occasionally, when i'm really fighting to not cum, the "no, no, wait, wait" ends up being out whispered and i can hear Master laugh. But sometimes he'll coach me "that's right, you wait until i tell you to cum slut". Unfortunately that totally turns me on making the situation worse. LOL

Bottom line, turn your mind away from your orgasm.
