Do you have interest in experimenting more to see if you can't find ways of masturbating you do like a lot or reach orgasm during? I ask because it's sounding like you're feeling pretty apathetic about it. If I have that right, it's not going to make much sense to suggest you experiment some more, because if this isn't something you actually strongly want to do, why do it at all?
This might sound silly, because to some people it's super-obvious, but you do know that you don't have to masturbate (or have any kind of sex) if you don't really want to, right? Erections come and go, as do feelings of arousal, so even if those are ways of being you don't want to stick in for too long, so you're masturbating because of that, you can just wait it out and it all passes pretty quickly.
If I'm reading this wrong, or you feel apathetic but not so much so you don't want to explore this more, holler, and I'll talk about that.
