Upon further research, having what is physiologically defined as an orgasm without producing an ejaculate is impossible outside of having a prostate (or semenical vesicle)problem. You can have something that feels similar to one (and that provides a lot of pleasure) but it's just teasing yourself. Colloquially it's called "edging" and it's tricking your body to produce the semen and then not release it so that when you finally do cum it gives you a huge load. If you do it frequently without cumming then it can cause prostate infections.
Basically, when you think you're cumming just stop stimulating yourself and tighten up your pubococcygeus (PC) muscle and focus on not cumming until the feeling subsides. Then go back to stimulation. If you do it a few times (it can be stretched out over the course of a day) and then finally go you'll release several orgasms worth of semen and cum harder than normal.
Yeah that's a more deatailed explanation of it, but the only negative stuff i had with tao is that it can sting a little after if you take a piss otherwise it has been just nice moments :D
