Super-O...almost???

If you've read my other posts, you will have seen that I have had some pretty intense experiences with and without my Aneros. Just now, I had a relatively new one that I wanted to share and get opinions on.

It started off fairly typical, p-waves, contractions, and lots of dry-o's...very pleasant. After about 45 minutes, I felt my anus try to push out the Aneros. I think this was the pull-in, push out feeling others have described. This has happened before but not with nearly the force that I had with this one. I felt that the rest of my body was relaxed and I wasn't trying to push out, but my anus was. It was extremely strong. It was sort of like a cramp; not painful, but completely out of my control. I rode with it for a bit and my penis got a very full feeling (not erect, just full) and I got a little bit of pulsing there. It scared me because of my recent issues with hemorrhoids. I didn't want to push out too hard. So, rather than take a chance, I turned my mind elsewhere and concentrated on "turning it off". After about 30 seconds or so, the activity stopped. I guess we'll see later on today if I created any new hemorrhoids. I sure hope not.

So, please help me understand what happened. Is it typical to get this very strong pushing out "cramp" when building to a super-o? Does this sound familiar to what others have experienced?
