Your statements are insanely dangerous to male health. Yes, there are methods to get the fluid build up out of the prostrate without orgasms - but these methods are not reliably and steadily available to most men, and even if they were those methods still do reduce the prostrates ability to empty itself (i.e. to ejaculate) permanently. And that is a damage no men wants.
The fluids start to solidify after only several hours, and that becomes a serious problem after a few weeks... It's difficult getting solidified build up out of the prostrate, and that's what starts prostate inflammation. Ask urologists about what they find in older mens hardened and enlarged prostrates - it's crass, and it comes from not emptying the prostate in a satisfying way. It really is a problem.
So all this caging and denying can end with prostate problems far more problematic than most men imagine. Don't do that for any longer than a nice kinky evening session with your partner. And then ejaculate the way it's intended and healthy.
When your prostate starts hurting in a very specific way you'll know what I am warning about. You don't want your prostate to hurt in that very specific way. You really don't want that.
