Made some progress and what I learned

I made some progress during my last use of the Aneros. Despite reading much of the information on this website and instructions my previous attempts did not go far.
This attempt was at a hotel during the evening. I did all the normal things during the initial phase - enema, shower, internal lube, etc. This time I used an adult DVD while I relaxed on the bed and prior to insertion. After insertion and more relaxing watching the DVD, I got what I thought was a cramp in my foot, as I had in previous attempts (I have been prone to leg cramps since early adulthood). I just tried to relax more and I felt a few anal twitches. Thereafter, I felt a couple involuntary penal pumps. Went on my back with legs bent. A few more anal and penal twitches. However, I could not hold the position so I went to the side of the bed. Throughout I was giving light contractions like a Kegel exercise. I really was just experiencing more light anal and penal contractions. It seems like my favorate position is face down on my knees on the floor so I spread out a towel and assumed the position. I just could not get beyond using the previous light contractions so I got the Aneros as deep as I could and contracted as hard as I could. This seemed to get me over the hump as I had a series of ejaculations without any fluid. However, at some point I dumped all the prostate fluid, but I do not know when. None seemed to last that long. Sometimes my penis was erect. Sometimes my penis was in a flacid state. A few times it felt like my inside was completely filed. Finally, I had a stronger ejaculation, so I ended the session. I did not even want to end the session with masturbation. When I got up, it felt like my legs were completely exhausted. I don't no exactly what all happened, but it was certainly better than previous attempts.
What I learned. 1. Using an adult DVD helped. 2. I did not care about my briefing technique. 3. I think the cramping in my legs were actually an indicator of what was to happen rather than what I experienced in the past. 4. I think I misunderstood the relationship between contracting and movement of the Aneros. Previously, I used to contract and at the same time move the Aneros in and out. This time I left the Aneros in place during contractions and only did in-and-out movement when I had to rest a few seconds. I learned that for me, in-and-out movement does very little to start anything. 5. The Aneros has to be in me as deep as possible. When there I found some muscles that I did not realize were there and these were the ones that I need to use to get things going (I could use some help from users to identify which model is the longest of the models because that is the one I need). 6 Knowing of these muscles, I try to exercise those when I do Kegels.
Problems that remain: I had to contract very hard to get to the pleasurable point that I got to. The hard contracting took away some of the pleasures. I probably experience some that I did not even know about (witness the prostate fluid dump that I did not know about until I had finished). I think I need a longer Aneros to get deep inside me. Finally, I don't think I know for sure what all happened. I don't think I got to a super-O. But I don't know exactly how far I got.

I would appreciate any comments from users. I am sure the comments will help me understand and move toward greater things. Definitely worth trying more times. Next try - in the same hotel as I will be out of town on business. Have a great day everyone.
