where does the cum go when you orgasm and flex your pc?

When i orgasm i can flex my pc and stop ejaculating, but i was just wondering where does this cum go? Is it bad for your balls, or prostate, or anything down there to keep all that sperm clogged up in your balls?

Im basically asking if stopping ejaculate during orgasm is bad for anything.

It becomes a “retrograde ejaculation” and IIRC, can be a causitive factor in prostatitis.

The only “fluid” that comes from your balls is sperm and this constitutes less than 5 percent of your ejaculate volume. If you force-stop an ejaculation, there is no way that either the sperm portion or the fluid portions from your seminal vessicles and prostate can go down into your testicles. It’s like MrP-P said. You can congest your prostate; not because everything goes back in there, it doesn’t. Instead, some built up fluids remain there when they ought to be getting an exit. Better if you cum pretty frequently, ejaculating forward, and clean out your pipes now and then, so to speak.

A danger of retrograde ejaculation (fluids backing into the bladder rather than out the urethra) is if you do this a whole lot you can weaken the valve between the ejaculatory duct and the bladder and end up ejaculating backward quite often. You may not want that.

My advice if you want to learn this sort of “edging” is that you bone up on male anatomy, learn the difference between the sensations of retrograde and forward ejaculations and learn to prevent the backward ones. That ain’t easy, but it can be done.
