Giving up orgasms completely and replacing them with ruined orgasms (we like to call them perfect ejaculations instead) is a tough job, and requires lots of supervised masturbation and practice to minimize and eliminate pleasure and orgasm from the picture and just release semen gently and beautifully.
This is littlesubsleep's baseline training video - a self ruined orgasm in the shower. You can see that he does a very good job for a first time, and is brave enough to keep his hands completely free of his penis as the orgasm takes hold. He's practicing a very nice "stand and deliver" technique and we see some good semen flow -- but we can do better. He stroked far too hard, too fast, and kept stroking too close to his orgasm ... you'll notice definite tell-tale spurting there. But he's committed to doing much better! No more orgasms for you, littlesubsleep!
