Been in the same situation with my friend we compared cocks when we were around 12-13 mine was a bit larger and I had hair. We got boners and touched each other for one night nothing more again. I was always curious if his cock got bigger we were 18-19 so one night we got together and I got comfortable and undressed to tee shirt and boxers we played video games for a hour or so and I made sure my cock would peek out of boxers this continued for a while I could tell he was looking at my dick so I would let it stick out the whole time. He was about ten feet from me .Then we started playin another game where he was closer to me so I left cock out I could tell he was looking at it so I decided to start talking about sex master bating ect and just asked if I could c his cock by then I had a boner and was hard to hide, he said u first so I stood up and my cock was inches from him in its glory, he was shocked that I just showed him and said give me a sec to get hard, the whole time he was jacking off before I knew it pants came off and cum was flyin I said wow he let me touch it and compared cocks mine was just a bit bigger but not by much . We put them away and never did it again see each other off and on but never do anything
