I Think i had a Super-O my first time out...maybe?

Hello all!
First of all i want to say what a great piece of equipment my new Aneros SGX is, and how helpful the forum has been for my newbie need for information. Good to know that there are other men out there interested in learning more about their bodies. Men whom are willing to try something "taboo" that could not only be a new pathway to pleasure but improved health.

So a little background so you know what my experience level with anal pleasure is. Im 40 - soon to be 41 - in a great marriage with a woman and have over the years grown more interested in anal/rectal pleasure. I would consider myself bi-sexual (yes she knows), but have only been with 3 men in a sexual manner and have never found myself romantically interested, simply turned on by the male body - in particular the penis. While i have performed oral quite a few times i have only been penetrated by a penis once. It was quite large and thick and i did have some trouble being comfortable with it at first but he was patient and managed to give me some pleasure by the end of our session, more so than i had expected. Shaking legs, waves of energy spreading out from my anus - a warm full feeling that really interested me. I had in the past used vibrators and small dildos, so i understood how being penetrated worked, but he was only able to get about 3/4 of the way in (whats 3/4 of 9 inches?) as my rectal sphincter would not relax. Also i am a skinny guy so everything is quite tight in there. Anyhow, after that experience i wanted to find a way to train my muscles to be able to accept penetration further inside.
This led to me researching the Aneros. I was skeptical but after reading the forum i ran out and got the SGX and used it that same day. I started off with the necessary cleaning (no details need be told here we all know what that means), a long shower and massage of the perineal and anal area. I did not touch my penis during this time except to clean off, put on some light porn in the background and prepared my area. I found that i cannot get enough lubrication on the SGX for easy insertion nor can i use my fingers to lube the canal very well, so i use a lubrication syringe to do the job. I prefer WET to any other lube and it seems to only need re-application after an hour or so. I started off on my right side with my left leg up by my knees and inserted and simply let it stay in there without contracting it voluntarily. Well after about ten minutes of relaxation, trying to just enjoy the fullness of it, i found that my anus had other plans, it started contracting involuntarily already. It started slow and increased in intensity pretty quick. A mild erection soon turned to more turgid and after about 15 minutes of this contracting i started feeling small waves emanating from my prostate, anus and perineal areas- mild at first. I then moved to all fours and that is when things started getting more intense. My anus was gripping the SGX pretty tight so i relaxed and let the natural rhythm take over. Sure enough about five or so minutes later i had a large amount of prostatic fluid flowing from my semi-hard penis, and it kept coming. I was already moaning and twitching and occasionally bucking my hips as the aneros gave me my first successful prostate massage . I had tried with my fingers with little success. This went on for about ten minutes and the flow then stopped. I tried getting on my back and put a pillow under my lower back to keep the handle from digging in to the the bed. In this position the same involuntary contractions started to happen and after a while my legs would twitch and my hips would buck and a little while longer i started to flop around the bed like a fish out of water, completely not controlling anything, i in fact tried to stop it at one point it got so intense. I had about three of these crescendos of pleasure ending in the involuntary bucking and twitching. All the while i am contracting only slightly and the involuntary contractions would start up again. It was as if my rectum wanted this thing inside it and knew exactly what to do. This is all after about 45 mins from the start of the session. I then got up to try walking around with it inside me and Holy Crap was that another level. I would walk a short distance in my hotel room, and soon my legs would buckle and my hips stated bucking again and the SGX was almost... well...*ing me i guess. I had to hold myself up and eventually it got so wild i was almost yelling, saying "Yes, Yes, yes oh my *ing god, Wow" I would start whimpering and whining too. So i got back down in to the spoon position and let what i think were super-o's keep coming. More flailing and bucking and a good amount of pre-cum came out, though i do not get the prolonged erection like others have. Finally after and hour and a half i had to stop. I cleaned up again, made myself a drink, and despite my best efforts i was so turned on that i had to masturbate, which i did. I have never seen as much semen come out of me as on that day. I am not a big cummer by any standard so this was wild.

Subsequent sessions have seen similar results, though not quite as intense, but the in voluntaries seem to come sooner, I think i may have to spend my first 15 minutes or so in complete stillness but i love the feeling of it inside me so much it is hard to wait.

So did I have s super-O guys or am i just building up to a much more intense level in the future? Also any tips concerning the Aneros or anal penetration in general would be appreciated. I think my wife is going to surprise me with a guy to share on my birthday so i want to be ready to enjoy everything about the experience - Wink wink.

Thanks!!!
