Can I have some advice on prostate orgasms?

So I’ve hit my prostate with my lubed finger, it feels good and makes my regular orgasms better, but i’ve never experienced earth shattering orgasms just from the prostate alone. I was thinking about getting an aneros but I’m not sure because just having a finger in my ass on my prostate doesn’t feel amazing to me. It feels good but not amazing if that makes sense. Am I doing something wrong or does the toy make the prostate just feel so much better?

Also, I’ve heard the female g spot sometimes doesn’t feel like much, but usually once someone has one g spot orgasm they can easily achieve it again, is this how the prostate works. Also one more question, once you have a prostate orgasm does regular sex feel better?

tl;dr – I’ve stuck a finger in my ass on my prostate, it felt good but nothing close to an orgasm, am i doing something wrong? Also once you get a prostate orgasm, does it make PIV sex feel better, and is it possible to get a prostate orgasm during PIV?
