My journey from "its ok" to "OMG". Plus a few questions. Please help.

Hello. I have been using the Aneros for about 2 months. Having read up on the different models I chose the helix syn. At first I was not impressed. My first couple of sessions were pretty uneventful, some ok feelings but nothing much to brag about. After doing some more reading and research I decided to stick with the do nothing technique. The helix was giving me the slight sensation of having to pee ( guessing this was from prostate and contact) even though my bladder was empty. On about my 4th session I noticed that my body was trying to hold back the sensation of having to pee. It was like my body was trying to stop me from peeing even though I didn't have to. Soon it felt as if every time I had the sensation of having to pee my anus and my PC muscles would spasm slightly without my control and developed a small rhythm ( usually last in 15 to 20 seconds at a time. I'm guessing these were small involuntaries, right??? By about my fifth and sixth sessions I had learned to hold on to the sensation by ever so slightly Contracting my PC muscle, but always letting the do nothing technique get things started. This would cause the involuntaries to last longer and be stronger. What's funny is the more I tried to relax the harder and Fuller these sensations became. After a few more sessions a couple of new feelings or sensations developed. The rhythm of the contractions between my PC muscle and my anus would speed up and become so intense that they blended together in one large contraction that felt amazing but only lasted a few seconds. Afterwards I just completely relaxed back to the do nothing technique and the contractions began again. This time a new sensation was added to the experience. Not only did the contractions between my PC and anus become bigger and stronger until building into one contraction again, there was also this intense feeling of fullness inside my rectum. It was as if my butt was trying to push out the helix while my anus was trying to pull it in. All the while both of these sensations, the pushing of my rectum and the pulling of my anus we're putting tremendous pressure on my prostate. The three sensations combined actually had me holding my breath while at the same time mumbling something along the lines of, "oh shit, oh god that feels great". This happened 3 times for about 10 seconds, each time being about 10 seconds apart. Note that during none of my sessions did I have an erection nor touch my penis. What was this?? Do others sometimes feel the same thing?? Have other peoples journeys been along the same lines as mine??

Since this time I have been unable to reproduce the exact same feelings. However, in my last few sessions I have gotten erections which in my mind are basically caused by the pulsing between my prostate and my anus as if the feeling is also traveling up my penis. When getting the erections the sensation is very similar to the buildup of a traditional orgasm. Once my penis is fully erect and very hard the pulsing between my PC muscle and my anus and stimulation of my prostate actually make it feel like I am having small to regular, yet sustainable orgasms that last for a matter of minutes and come just a few minutes apart from each other. WHAT A FEELING!!!

I wish I could combine the feeling I had of fullness in my rectum, tightening of my sphincter and stimulation of my prostate along with my erections and the feeling of the sustained orgasms. Would this then be the infamous super O??
