Hey Worldz,
I know you weren't buddy, I was directing it at those were telling the OP he wasn't straight if he was talking to a guy about a girl and getting off.
I was talking to a friend on the phone, just about everyday stuff. During the conversation he brought her up. I told him that I had been with her too. We started comparing notes, like positions, sounds, etc. Somewhere along the way, I mentioned I was getting horny just thinking about it, and he said "Me too". We kept talking about her and how good she smelled, tasted, how she really got into the sex, and really started getting detailed. At one point, I noticed his breathing changed a bit. I jokingly said "You rubbin one off"? I could tell by his silence that he was a bit embarrassed.
I said "It's cool, I am too". We kept talkin and strokin. Pretty soon I could hear that he was cumming, which sent me over the edge too.
It was a cool experience.
If that's gay, so be it. I personally don't see it that way.
