Endurance

I've always wanted a guy to give up his orgasms. Let's say for a week, as a challenge. I would tease him. Purposefully send dirty pictures, or press against him when passing by. Really testing his willpower to resist. It would turn me on to see how he starts getting aroused in inconvenient situations. The bulge in his pants becoming more noticeable as days go by. Watching him get more sensitive over time. Never able to hide his reactions, or keep quiet. And on the final day tie him up and ride him for all he's worth, before he has the most intense orgasm from all the build up. Then only untie him if he agrees to try for two weeks this time ;)
