Is EVERY male capable of achieving an orgasm through prostate stimulation alone?

About a year ago now, my lady suprised me with an Aneros Helix Syn. She had been doing a lot of research on the male prostate and learned that men can have much more intense orgasms through this form of stimulation. I began to inform myself about it and was completely sold on the idea.

She is such an amazing partner that she helped me the first time I went to use it. Unfortunately, despite all the prep and foreplay, I was unable to achieve an orgasm or ejaculation. Neither of us engaged in direct stimulation as I wanted to cum hands-free; letting the device with my contractions do all the work. The most I was able to get out of the experience was a very slight sense of pleasure from the site of the prostate and a LOT of precum…

After an hour, we decided to suspend the experiment and have sex. I left it inside me while I fucked her. Still, when I came inside her, the intensity of my orgasm/ejaculation was on par with our general sex routine.

My question is this… Are not all men able to successfully achieve a climactic experience this way? Or, does it require a lot more experimentation and experience?

We tried several times since with similar results. Any input or advice would be very welcome. Thanks! 😊
