Does your G-spot get aroused on its own?

This question may sound odd.

And yes, I am fully aware of where the G-spot is located.

I just want to know if you ever had experienced, while being in a state of arousal, sexual pleasure on the g-spot.

It's like, you're alone, aroused and it feels like someone is fingering you down there intensively.

It happens to me a lot, though! O.o
