Um, yes! When I was in high school I became friends with a nerdy guy who turned out to have a really big dick. His parents were caretakers of an apartment building & I would accompany him home a couple days a week & we would smoke dope in the closet of an empty apartment.
These closet dope-smoking sessions turned into J/O sessions. His dick was porn star huge and he let me play with it while while we passed a joint between us, while I talked about how big it was the whole time it was in my hands. He loved hearing how much I admired his big dick and how I wish mine was that size.
The reference to the nerdy guy, reminds me of something which happened when I was in high school. I was a big jock, 6'3", 190 lbs, well-built, muscular, hairy chested, very athletic, played football (high school and college). Definitely BMOC. There was a nerdy kid who lived down the block, about 5'10", thin as a rail, not muscular or athletic, pale, little or no body hair, glasses, kinky-ish hair. He had a basketball hoop in his driveway and every time I'd pass by he was always bugging me to get to play. I always put him off because, well, frankly he was pretty geeky. Okay, okay, I was a snob!
One day I finally let in, and we shot some hoops for awhile. Later on we went upstairs to his bedroom (his parents weren't home) and after awhile, somehow or another, the talk got around to sex and girls (we were both virgins!), and eventually size. . . which led to measuring. I believe it was his idea. He confessed being a little worried about whether he'd measure up or not, and I admit I was curious, too. Anyways, when he pulled down his pants, I was dumbfounded. He was hard, and almost twice my size. When he put the ruler to it, he was about 7.5 inches. And thick. I was very self-conscious when it came my turn. Mine looked like a little boy's next to his. I blurted something about how big his was. He seemed genuinely startled by the size difference betweenus and commented rather snarkily on being surprised at how small mine was for such a big guy. He definitely rubbed it in, asking me if didn't I wish mine was that big, etc. -- payback time for my being such a snob all those years.
After that, I was always a little self-conscious around him and never got over how a geeky kid like that had such a big cock.
