Personally, I believe in having as many orgasms as possible, yet only achieving orgasm for a purpose. You can learn to have sex and masturbate w/out achieving orgasms. You can keep this process going for an indefinite amount of time. Basically, if you are going to orgasm, direct it towards some purpose, it is extremely powerful. If you want to have sex or masturbate, after "delaying" the orgasm a couple of times, you will have achieved all of the pleasure you desire and most times an orgasm is unnecessary. When you do orgasm though, try to have a real purpose for it. You can use that energy to your "advantage".
