When exactly will it “click”?

I haven’t done prostate play in a while, so today I grabbed a dildo and got in my bathtub. I probably played for maybe an hour and a half, but around the hour mark I just started jackhammering my dildo into my asshole. And I honestly started feeling some pleasurable feelings, it felt like I needed to take a piss but in a sort of good way, but it didn’t really go anywhere… like I was just jackhammering away and it didn’t even feel like I was going to cum, just like I needed to take a piss. I didn’t even end up finishing through penile orgasm either afterwards. How exactly does it go farther? I thought I was getting somewhere when I felt like I had to pee and then it just went no where. Anyway give me your feed back
