have you ever touched your mans "G-Spot"?

So I've heard that a mans "g-spot" is in his ass, and it's actually really pleasurable for all men straight or gay. I stuck my finger in my boyfriends ass for the first time and I've never heard him moan like that before... he enjoyed it so much that when he came he never came harder. I would jack him off with one hand and finger his ass with the other😅 He kept telling me it felt so good. I'm so new to this and wanna hear stories if you've ever done anything like this before.
