Anyone ever experience a coregasm?

I was working out with a group of friends recently and we were all doing pushups. I started to tire out and did knee pushups and suddenly I felt this very intense pleasurable feeling coming from my prostate. Against my will I was kind of moaning and my friends asked if I was ok while another said, “he’s having a coregasm” looked it up afterwards and had no idea it was a thing, but damn did it feel good. Is this what bottoms feel when they get fucked? Anyone ever experience a coregasm?
