The earliest experience I can remember took place when I was maybe six years old. The church ladies were holding a PTA meeting at the (vacant) parsonage next to the church. I wandered into the kitchen, just looking at the details of the house. Some other kids, a boy and his brother, were also in the room. I don't remember how it started, but one of the boys flashed his penis, and I was really surprised to see that he wasn't wearing any undies beneath his Adidas shorts. I asked him about it, and we went to the playroom inside the church for more privacy. I never showed mine, though. There were a few other "glimpses" over the years; boys always seem to pull their pants down to their ankles until they're about eight or nine years old when they use the toilet. At that age, there isn't much remarkable difference in size or shape between penises, but I wasn't complaining, haha! The first time I had a real "comparison" was in the 6th grade. I was standing at a urinal before lunch recess, and I noticed that the "new kid" had a different look to his penis. It was longer than most other boys' penises I remember seeing, and it was pointed at the end, with no head! I asked him about it when we were serving detention together, and we dropped our pants in a dark corner of the room. We touched each other a bit, but since this was a privately funded school, the sex education program made no mention of anything beyond the basics, and I didn't know that the foreskin could be manipulated. We messed around a few times after that, but he seemed reluctant to go very far. When I graduated to the public middle school, I was determined to see as many penises as possible! Changing for gym was the most obvious choice, but the better (and safer) option was watching the other guys at the urinals. And I wasn't disappointed, hehehe! Seeing other guys' penises, with their different sizes and shapes, the color of their skin, the texture of a vein, and especially the pubic hair, or lack of it, made me feel better about the quality of my own "boyhood". I started growing pubic hair when I was about ten or eleven years old, and I felt reassured knowing that I had a head start on most other boys in the locker room. I have never felt insecure about my personal size...not even when my brother-in-law got out of the shower one morning after a sleepover. I'm aware that a guy's "size" is completely random, and nothing you do can change it. So, it doesn't help to worry about whether I'm "bigger" or "smaller" than someone else. As long as it works, I don't care!
