Finally “unlocked” some crazy stuff last night, entire body is sore today

I’ve had this progasm for 6+ years and have never seriously taken the time to use it. I remembered I had it and read up a bit, and then had a three hour session last night. WOW is all I can say

I didn’t achieve a super O or anything but hoping someone could give me advice based off of what I did feel

By hour two my body was twitching like absolute crazy. My arms, legs, stomach, etc were all super contracted and out my control. I’m sore today. I felt like I kept having to “hang on” and at several points my body was shaped like a person on the receiving end of an exorcism 🤣 it was so crazy. I just focused on the feeling and held pressure at around 20%.

I do remember feeling a couple really sharp electric feelings in my dick and had lots of precum. My dick was dancing all around and anyways my body was just completely in a different zone I’ve never felt before. Waves of crazy feelings leaving me completely out of breath.

What’s your advice for next time so I can take it even further? I def didn’t get super O but hoping one day I could. Hadn’t used this thing in years so I’m glad I had some success
