Not sure if it was P-wave or SO

So, a couple days ago I had a session, and it's like I forget what's going on, and boom pleasure rides over and over and over. Maybe 60 seconds. Yesterday got what I'm guessing was a mini-O.
Now today, I wasn't having much luck with my Maximus, or Progasm, so I slapped in my Peridise for a bit. It was feeling really good, putting pressure with the small bulb on my anus, and was pretty mobile, so I was like, what the hell, and threw in my Helix. After relaxing I feel a tap-tap-tap that doesn't stop, so I go with it. Next thing I know my entire body is vibrating. It was is I had a giant vibrating bed under me. Wasn't sure what it was, so I kinda concentrated and made it build stronger, and stronger again. This lasted about 10-15 minutes of just high-frequency vibration. It started to subside, and left my extremities, but I was able to build it back again. Then I just relaxed and it was gone. Now, is this just a P-wave?
