Looking for advice/explanation

Hi everyone! I’ve been toying around with prostate massagers for little over a year now and have really enjoyed my experience so far. While my sessions generally don’t produce involuntary contractions or p-waves, they’re still very pleasurable and a good way to relax.

In two sessions, about 6 months apart, I’ve managed to get these p-waves (i think). During those sessions (first with a leluv nero knock off toy, another with progasm) I felt the pleasure build up (as it usually does), but then suddenly the pleasure grew and began creeping up my body untill my whole body was “tingling” and feeling all around very pleasurable. There were no muscles clenching, I kept on doing what I thought felt good and the “wave” of pleasure passed after 10 second on the first time and after approx. 1 minute on the second.

The first session I did manual contractions until it got to the point where I tried to keep relaxed, but the contractions sort of were automatic. After a while this resulted in the first wave of pleasure.

The second session I tried breathing deeply in and out of my belly, and after a while the wave came and passed.

Since these two sessions have been so pleasurable, my question stands: is there a way to “cheat” yourself into feeling these sensations on a regular basis?
