Help! My sessions end with hfwo...

After several years of off and on usage with little results, I have finally made significant progress the past few months! My nipples are alive and are the main driver in arousing my prostate. About 3 months ago in a session with the HIH 950 I became aroused to the point that I had my first hfwo. It felt awesome and I was pleased with the result.

Since then I have continued having hfwo's with the HIH 950, PS-New, Eupho Trident, and MGX Trident. I do enjoy them, but at this point I'm beginning to think it might be sabotaging my path to a super O. After doing some research I try not to clench as I feel and wet o building but they still seem to happen. What can I do to prevent the hfwo from happening and progress to the super O?

My technique is to insert an aneros and relax for a few minutes. Then I begin to gently rub my nipples. At this point I begin to experience p-waves and start getting a partial erection. Then aneros begins to start dancing and bumping my prostate. I start to leak prostate fluid and then my prostate starts throbbing and I get a full on erection. I'm able to keep this going for about 5-10 minutes before things build to the point I feel something big is going to happen. I try to relax my pelvic muscles but they still move the aneros and I have a hfwo.

Am I right to think this might be sabotaging a super O? Or I am going through the natural progression on my way to a super O? Any advice or tips would be greatly appreciated!
