I wonder how much does prostate play amplify my penile orgasm.

I heard from many people that even if they haven’t experienced their first prostate orgasm, prostate play amplifies intensity of their penile orgasm like 3 to 10 times. Does it really ampliy it that much?

Yes, No... maybe! There is no way of predicting how YOUR body is going to react. Some men have no or little amplification of their pleasure intensity with combined penile and prostate stimulation. However, most men do report increased pleasure from having a Super-T which can become a trap in itself, i.e. you can get habituated to using an Aneros to have Super-T's and retard your learning toward a Super-O. I would caution you to do more research to avoid falling for Super-O Myths & Illusions and the hyperbole touted by others. If you expect your orgasms to be "...3 to 10 times." more intense you are only setting yourself up for frustration and disappointment. In early use of your Aneros you may not get such significant amplification but as you learn to focus on your body's sensory output your mind can aid in nurturing the feedback loop being generated by your massager. It is the continuing build-up through this feedback mechanism which amplifies the perceived pleasure.

Then is it that intense to the extent where you only have to make a noise or barely hold making noise?

You don't have to make any vocalization to enjoy the pleasure of a prostate based orgasm but if you feel the urge to spontaneously emit groans, moans, growls or any other vocalization then I encourage you to do so. Suppressing these natural impulses will only diminish your enjoyment.

Because as a person who have only experienced regular penile orgasms, I really want to experience such intense penile O my self.

Then get on with your Aneros journey and start your adventurous experimenting. While reading all your can (especially the Aneros WIKI) about prostate massage and techniques is all well and good, there is no substitute for personal experience.
Good Vibes to You !

thank you so much @rumel, now I genuinely feel a lot better and I think I can almost get rid of my female-O-envy if not all. thank you so much for your constant advice.

Great advice @rumel! I second about just having no expectations. It's most people's downfall, was even mine and still is sometimes! It's hard! But you just have to let go! @wooripsp

My traditional orgasms definitely increased in intensity since I started practicing MMO (which was about 9 months ago). The pleasure I feel outside of orgasm has increased even more. I also feel less drained after ejaculating, which is great. All this despite not being very successful with dry-Os yet. With that said, I still don't feel like they're worth it, so I stay away from them.
