I told you it took me almost 16 months to get to a level where it was causing significant pleasure. Some here take more some less
I just started with helix and tried it about 3 times, nothing. I thought the helix was nowhere near my prostate. But by the 4th time, I got a wonderful "tickle" on the prostate and shortly after, my balls and cock were hard as rock (don't know if this was a dry-O). Had some precum then. I could keep the tickle going for a long time. I found that after starting with light anal contractions, I switched to a "rocking" or slight "thrusting" motion while on my side and that seemed to get things going. Don't give up just yet!
