Body reacting but not the pleasure?

I don't know if someone had found the situation where I'm in (for years now - I use aneors since 2012) and managed to get "past it" somehow.

In short I've had some "weak" dry os but they're extremely rare for me. I call them "weak" as they're much weaker/less pleasurable/satisfying than a normal ejaculatory orgasm, and so far I didn't feel anything "mindblowing".

But that isn't the question, but this one:

Like I said I generally don't have much reaction to the aneros. Most of the times it's just a small background pleasure and nothing else (I generally use do nothing approach).

However what is very common for me is that when I get aroused I get hard and my prostate (pc muscle?) and penis starts throbbing, something like once every 2 seconds. This can happen quite quickly in a session and lasts for some minutes before subsiding and happening again later.

When this happen I don't have pleasure, it's pleasant but I wouldn't call it pleasure.

In the rare cases I had dry os the physical reaction was exactly the same with the exception that was way more pleasurable.

Sometimes I also get into that stage where I start talking to myself and all that (the alteration of consciousness people talk about I guess?). When this happens I am feeling pleasure but again it's not as good as the few dry os I had.

So basically it's like my body is doing things "right" but actually I am not having much pleasure. I've had orgasmic pleasure from aneros but it's very rare. It feels like my body isn't fully interpreting the "dry orgasms" or something.

Did anyone felt something like this and if so did it "click" eventually? It's a bit frustrating as 8 years later dry os are still super rare for me and it feels like there's much more pleasure to get from this.
