First time user experience

Well let me begin with that im new to aneros and have only bought my first toy last week. I have had some other play prior to this but not a prostate massager. I went and bought the progasm ice because i heard that it was so filling and easy to use. Well only to do a bit more research i found out some people said it was more of a experienced users toy, i said screw it i dont care why would i buy another right now when i JUST bought this one. Anyway, my first session with the aneros i was your typical first user. Expecting the big O, after getting it in i started contractions right away and was waiting for this great feeling to come around, well after about 30 mins i was already getting tired out because i have never used my pc muscles soo much in such a short span of time, shortly after this i was getting frustrated and NOT relaxing like i should have and well besides using the toy for myself i used it to enhance sex with my wife, so went and did that and it felt great with the aneros in once orgasm came. Cleaned it up and put it away for another day to try again. Well after doing a bit more reading (which i believe i should still do more and help myself in anyway possible) i found a really interesting post on this website about what the feeling would be like and how i should try and achieve this super o and enjoy the aneros as much as possible. Well needless to say that his detailed advice i believe actually got me to my first super o on my second session as of last night. Now im not entirely sure if i have gotten it 100% maybe it was just a good feeling or the start of the super o im not sure, that's why i am here to ask your opinion on the matter.
In order of sequence how i prepped was emptying my bowels, shower to relax and kind of arouse my self a bit down in the region. Looked up some porn (said arousal was a big help which i did not do the first time) and well once i was plenty excited i got my aneros all prepped and lubed up and inserted and relaxed for about 10 mins and just concentrated on breathing. Soon after that i started to work my pc muscles very gently trying to hold them for a long time and let go. After only about 5 mins of doing this i actually got an uncontrollable shake in my hand, was very odd at first but moments after my breathing started "vibrating" really quick breaths as i was breathing out and in like i was shivering. Odd i have never had that happen before so i continue to relax and go along with it and just before i know it, my legs start to shake and im feeling a pretty great feeling, very different from any other pleasure i have received. My aneros was going in and out on its own at this point with no effort coming from me, about 2 mins of this is quit at a snap of a finger. I laid there out of breath like wow that was different. Felt very tired and kind of exhausted after, didnt think i would be able to get that again but i tried anyway and not only a couple mins later did i get the same feeling in the same order and all.
Now here is my question did i infact actually experience a super o or just the beginning stages of it? Also it was dry no precum or anything, i feeel like the progasm over reaches my prostate a little but i cant be sure, i know that when i really rub it even with the progasm i get that feeling of having to pee but i dont get that when its in all the way. idk anyway, just wanted to fill you all in on my exciting moment! 😀
