Made some real progress, but unsure if it’s the right kind?

So I got my helix syn a few months ago and while my first session was a decent success, my subsequent sessions were kind of dull. I didn’t feel my prostate at all, despite leaking precum and what not.

Until yesterday, when I followed this guide’s advice: https://www.extremerestraints.com/article/aneros-detailed-instruction to hold my sphincter’s contraction at half strength and to start playing with my body wherever I’m sensitive. This lead me to play with my nipples a bit while keeping my sphincter at half strength, at which point my prostate finally “activated”. I began to finally feel some tingling in my prostate and I started to actually feel my toy roll over my prostate during contraction.

Now the problem is that I only feel my prostate being stimulated as long as I’m rubbing my nipples. When I stop rubbing my nipples, I stop feeling anything in my prostate despite doing the exact same movements with my muscles as before.

I read on the official forums that it’s relatively common to get extra pleasure from your prostate when playing with your nipples (or any other sensitive area, except your penis), and I’ve also read of people rewiring their nipples to feel pleasure from the prostate without having any toy inside you.
