This thread reminds me of the first time I suppose I noticed a bulge. It was in eighth grade shop. One of the boys (whom I had been in P.E. with in seventh grade) was very tall, very thin, and well endowed -- not huge, but certainly mature. In shop, we sat on stools. He was across the table from me, his feet on the rungs, which gave me a good view. And I noticed how the fabric of his tight jeans (the 1950s) pulled up to show off a nice bulge. I certainly didn't think he was trying to show off; it was just the way his jeans fit. And I remember thinking, I'd like to look like that -- not because I wanted to impress people, but because it meant to me that this is how a man looks -- I was tired of being a little boy!
