What is the orgasm like with no ejaculation?

i want to pick up on a point that EB02 made. i can recall in my early years of ejaculation that i could have enough ejaculations in one day to essentially deplete my semen. at that point, the next orgasm was extremely intense with very little or no semen. i think this may well be analognous to the more intense dry orgasms many men experience after prostate surgery. keep in mind that those who have radiation treatment will also experience dry orgasms eventually. my day will come!
