Advice for a not-beginner on not reaching super-o

Howdy guys!

Middle-aged man here that has been doing some anal solo play for decades. Among the experiences are several models of Aneros toys, but they never hit the spot for me. Well, they do hit the spot, but they do not work. I find all models "sharp" and unpleasant to use. Whenever they move it feels like a sharp pin being pushed into my p-spot and it's just not good. I haven't tried them all, but I did try the classic and 2 more models, among one of these a silicon model in the hope this would fix the sharpness but it didn't. What HAS worked the best is a p-spot silicon toy that is more volumous with a big, round tip. It's clearly larger overall than the Aneros toys I've tried.

While this DOES feel great and has gotten me to pleasure waves, I'm getting nowhere on the super-o. I guess an issue with this tool that did work is that it involves manual movement. Another issue is that I never found much pleasure in just going anal. I need to touch the penis to a certain extent to get going. Doesn't have to be downright stroking or anything, just moving it slightly is enough.

But I would like to reach that super-o. Any advice to give in this situation?
