massaging the prostate?

so one night we were getting intimate and I was working on him, I was like; hey can I try something on you? *he had no idea* so he was like okay. I started massaging the gouch area on the outside of his prostate, he was like "whoa whoa, ohhhhhhh" he was close to cumming, and everytime I stopped, that feeling subsided. I finally finished him off and he's like, where did you learn that?! I was like, "I read about it". Then he responded," it made my orgasm more intense". Haha then I told him that, that's the male gspot and he blushed a little. And then he told me,"it's funny how you can find my gspot but I can't find yours".
