P spot question

I’ve started to feel some pleasant sensation from my pelvic region to my belly button after some weed and deep diaphragm breathing. Is this my prostate or something else? Just wanna know of I’m on the right track.

I also wasn’t using the contractions I was just relaxing completly still, felt my breath almost massage my prostate. Whenever I’d use the contractions I’d lose the feeling and get nothing else. Should I try to do the contractions or is it possible to super O while completely still?
