Reprograming apparently will be a long process

When my wife went to visit family, I finally had an opportunity to dedicate some time without limitations. Because of my recent non-events, I acquired a Helix Classic and a VICE in the hopes I could finally achieve a p-orgasm.
I have concluded that the neuropathy that I have in my feet from my chemo twenty years ago also affects my anal area. Because no matter what device I used, no matter how I relaxed, no matter how frequent or infrequent I tried contractions, no matter what setting I used with the VICE, all I got was great edging.
I have been careful to not get my penis involved. I tried early in the evening, at bed time, in the middle of the night, and in the morning. I plan to persevere, but it is rather disheartening.
After a little down time, my next effort will likely include the enhancement of marijuana. I am hopeful that it will push me over the edge.
Advice appreciated.
