A lot of Progress, but no pleasure

Hi Guys,
Im stuck and need some advice or help.
Im working with a bit longer with Aneros(4 years on and off) and i get some results, but no pleasure.
Mainly my body does a lot of Things but i feel no plessure in my prostate.
Fast Heartbeat, my pelic flore goes into auto mode and masagge my prostate, my Breath gets out of control und sometimes my head is shacking rapadly as would symbole a no, full body trembling and losing control over my body. But no plessure is building up. No P Waves are going through my body.
It feels like a ramp, some tension is building and the moment i let go my body takes over. After some time I clamp(as you would tensen your body to lift something heavy) and with a Kind of a push motion the aneros gets pushed onto my prostate and a small spicky energywave goes through my prostate. (its very regional). Sometimes with the wave i shoot some clear liquid out of my flacid penis.

No matter what approach I choose or what sensations I feel/pursue i dont really make any progress. when I let my body take over, it ends in clamping and, at the moment, much too early, without the waves. So I have to concentrate and relax at the same time, but somehow it feels like something is building up with a new approche, and when I give in to it, I come back to the same point.
There is a connection between arousal and the waves. Only when I am sufficiently aroused do I get the waves, and when I am very aroused (the best time I had so much ejaculate that a puddle formed, but my prostate only sent the same signals as always), I get the clear fluid.
But I get stuck at that point. I've known about the waves for two years and haven't noticed any difference since then, so it feels like a dead end, no matter how i want to solve the problem(for example: with a lot of nipple stimulation) i end up at the point where my body goes crazy and i dont make any actuall progress with my prostate. My body is showing more and more reactions and wants to take over earlier and earlier, making other patterns more difficult and the prostate still is silent.

Other feelings: tingling in the testicles outside of the session.
Sometimes during the build-up, it feels as if my legs want to start shaking, but it goes away when the body takes over.
Sometimes it feels as if I have pressure on my ears and then a strange feeling forms in my head and feet, which somehow feels as if my brain is just imagining what my body could feel.

(I already tryed brownies, but it nummens my sensation.)
Im open in answering questions, its hard to describe the feelings.
