Actually, I've been doing this for a while now and recently had some explosive results.

A few days ago while laying down and contracting the various muscles back there while visualizing something was massaging my prostate I had two back to back very intense non-ejaculatory orgasms. I've only had experienced it once before while using an Aneros (a week or so ago), which left me dumbfounded at how I was able to experience two without using an Aneros, especially so soon after breaking through.

Visualization is a very powerful tool it seems. I wonder if visualization while using KSMO is also effective, I'll have to give that a try.

Edit: Also wanted to add in that I was watching an erotic video when this happened, to get aroused enough that the visualization seemed to be more effective.
