“Disappointing” HFWO during second session

Hello,

So I (M25) bought an Aneros (Helix Trident) and received it yesterday. While I was waiting for its arrival, I checked a lot of the posts here on reddit to understand what it could do and how to “correctly” use it.

My first time was yesterday, and I think it was a decent first time. Got some satisfying “tingles” within my ass, feeling like pleasing sparkles, don’t really know how to describe it. Also got a lot of erections, as the new sensations of that unexplored territory were turning me on (+ i didn’t jerk off for like 10 days). Not much but I wasn’t expecting some major breakthroughs for session 1.
I tried again tonight. At first I was annoyed by the sporadic erections because they were distracting me. At some point I just decided to “accept” them and i could enter a better relaxation. At this time, tingles/sparkles appeared again. Then, I could feel a pleasing spot (in the ass) that I definitely know gave me sexual pleasure in the past and that i already tried to trigger before I knew all the prostate massagers’ benefits. As my penis was a bit “pumping” on its own, i let the feeling of the pleasing spot getting stronger and stronger and then … I came. Like a regular orgasm but with my feelings focused on the spot (i’m pretty sure it’s the prostate) and not the penis. Since I was not expecting that, I was like “wtf, this is it ?” and checked the towel underneath that was definitely wet.
