The SUPER O is too much....

I finally had my first super O, and it was great and all, but it was a bit too much...

I did the 11th finger method and just imagined the aneros striking my prostate. I fully concentrated on all the good feelings, and it hit me really bad, its like this force that hits my stomach, and i want to scream out, but i cant.

The crazy thing, and this is what i call "more than a super O" was when i started pushing in the aneros deeper with my hand, i instantly had convulsions, but there was this energy i wanted to expel, but i couldnt, all i could do, was scream...

Im not sure if im making sense, but has anyone actually nudge the aneros in right after or during a super O? if not, you should try it...
