Just like "rape" and similar pain/suffering concepts for an average middle class comfort-obsessed suburban thrill seeker, there seems to be a confusion about the "torture" part. Make no mistake, when performed properly, you will need to be restrained, and you will beg to stop it. Don't expect any pleasure. I can only compare it to the worst, most excruciating kind of tickle. And, I can only speak for males, no, it won't make you come.
First off, POT uses a different technique than simply continuing to stroke/pump the shaft after the ejaculation. I'm sure there are variations, but it is mostly focused on the upper, flatter part of the glans, opposite of the frenulum (the bridle). The corona is sensitive too. The most common motion is palming aka "polishing". Screwing the glans inside the fist is popular too. The lube (your cum, what else) and the right pressure are important too.
Second, while you may think I practiced it on some guy during a gay orgy to know that many details, it is possible to "torture" yourself, but just like tickle, it is better performed by someone else's (skilled) hands. If not for sensitivity, then for taking you over the edge ignoring your pleas.
Third, tickle of e.g. the balls goes hand in hand with POT in that ultra-sensitive state, along with stimulating other senses e.g. tickling (the inside of) the anus or repeatedly invading it. Not with a thick dildo/strapon many of you fantasize about. Forget those mainstream toys. Think about brushes, feathers, and other things depicted in the "sensory overload" femdom art for the best reenactment of. I am also curious how more advanced stuff like breath control would play in this scenario.
Fourth, I hope you are not circumcised, because that robs you of 50%+ sensitivity.
And fifth, if you have anything in your bladder, POT "palming" will cause a sharp uncontrollable urination urge, which plays very well with my kinks, but is definitely not mainstream, hence the breaks in the POT videos to let the victim catch his breath and avoid pee fountains. See my other thread for details: https://www.zity.biz/index.php?mx=forum;ox=display;msg=839168
A couple of classic videos. As you can see, no one palms the glans for longer than two seconds. Probably out of the fear of peeing, or perhaps due to the unwritten (or enforced) restrictions of the publicly posted videos e.g. to avoid the victim fainting. Would be interesting to see it taken to the limit. Tickling too.

I also remember a video of a guy tied to some pinkish plastic board and POTed with a vibrator. If you find it, note his convulsions and the feet curl. Definitely not fake.
I think POT works the same for women, and there can be direct correlations between the glans and the clit, but that requires experimentation, my vanilla GF is unfortunately not OK with. Or tickling for that matter. I am also curious about the urethral opening stimulation.
In any case it's far from traditional pleasure and it doesn't bring you release, unless the dominatrix also stimulates the underside of the glans, which she never should.
