Update to Has Anyone Else Experienced This?

Thanks to the replies from Clenchy, Rumel, and Helghast and my meditating on their suggestions, I am happy to report that things came roaring back to normal this morning with an hour long, continuous anal and prostate orgasm. To briefly recap, I had been having anal orgasms on a regular basis for several months. I stopped cold turkey for a couple of months and restarted a little over a week of ago.  Despite doing the things that I did prior and using the same toys nothing was happening when I resumed my sessions. 

I took their advice and concentrated on clearing my mind, relaxing, and destressing.  I went to bed early, cleared my mind, darkened my room, no electronics prior to bedding down and had a nice cool comfortable room to sleep in. I had a great restful night's sleep. I awoke around 4:30 AM with my cock straining against the bars of the stainless-steel chastity cage. My balls were swollen and I was horny as hell. I needed a session. 

I pulled out my box of toys and took out the very first Aneros toy that I had purchased back in 2006 - the Classic Maximus. For several reasons I got away from using it and turned to other Aneros products. I decided to give the Maximus a try after ignoring it for several years. 

I lubed the Maximus and inserted my lubed finger into my anus to get it all nice a slick. I then inserted the head of the Maximus and my anus latched on to it and sucked it into the hilt. I immediately felt my entire anal canal and prostate come alive. Everything was buzzing. I had not experienced anything like that with Maximus in the past nor had I with the MGX, Peridise, Progasm or Helix. 

I laid down and just concentrated on the wonderful feelings building in my anal canal and my prostate.  This was the first time that my prostate was buzzing more than my ass tract. The sensations going on were almost overwhelming. After several minutes of doing nothing, the clinching, the shaking, the moaning, and the humping started - it was pure bliss. As the session progressed, I felt a single large spasm in my prostate like when one comes during sex. Rather than multiple spasms it was a single large spasm. These single prostate spasms happened only twice during the session. I wear men's bikini underwear from Jockey. When I pulled down my bikini to remove the Maximus, there was a pool of pre cum where the head of my dick had been resting.  This is really unusual because after the radiation treatment for prostate cancer I had completely dry orgasms when having sex with my wife. I would come, but there was nothing there. 

I had never experienced a session like this one.  My anal tract and prostate have been buzzing off and on today, especially when I'm sitting on a chair. It is late afternoon and things have finally started to calm down. I only hope that I can have a repeat performance in the near future and hope that this morning's session isn't going to be a one and done.
