In the late '50s, Sears and Spiegel used to send catalogs to customers.  I remember at 8, 9, 10 years of age being interested in looking at the men and boys in the underwear section.  Although I didn't understand why I like to look at those pages, I knew that I was really into seeing the bulges in the front of their briefs and flipped through the catalogs whenever I could do it without being seen.
At some point when puberty kicked in in the early '60s, I remember looking through a Life Magazine that my parents had a subscription.  There was a photo of some rich Italian guy sitting behind the wheel of a boat.  The photo showed him from the knees up, and he was wearing a brief swimsuit that prominently showed his bulge.  I remember stashing this issue after the next one came in the mail.  I used to look at that photo and I was mesmerized by how big his bulge was and that he was wearing such a revealing swimsuit (I didn't know that such swimsuits for men existed).  I knew that I wanted to find a swimsuit that would show my little dick.
Meanwhile, a classmate in 6th grade and I became good friends.  One day we were playing in his basement and he asked me if I ever jerked off.  At that point, I didn't know about it.  He showed me how it worked, and I was quickly on board.  We became J/O buddies.  At first, we just jerked ourselves.  Before long, we started to jerk each other.  That was totally fun, and each of us liked having the other one get us off.  We jerked together through 6th, 7th, and 8th grades.  We went to different high schools, and lost touch.
The following summer, I began to notice other boys at the beach and at the lake, and particularly took interest in the boys who wore stretch swimsuits that showed the outline of their dick.  The local discount department store had an assortment of "knit swimsuits" for men.  They were the squarecut swimsuits of the day that were made from some kind of stretch material that clung and showed dick outline, especially the lighter colors.  I wanted to find a brief swimsuit like the Italian guy wore, but never found one.  I used the money that I made from mowing lawns and bought a red knit swimsuit.  I remember getting a boner every time that I put it on, and loved to wear it when I went swimming.
It wasn't until years later that my mom, my sister, and I went shopping for new clothes just before I began high school.  I spotted these clear plastic cylindrical tubes that had a Jantzen striped swimsuit inside.  The tube had printing on the outside with a clear outline of a men's brief that showed the striped fabric through the clear window.  I remember there was royal blue and white stripes and green and white stripes, and I was dying to take a closer look, yet instinctively knew that I shouldn't do it with mom and sis with me.  I went back to that store by myself and was "just looking".  Those Jantzen swimsuits were expensive for my means, and I would have to save for a long time before I could buy one.  By the time that I had saved enough money to make the purchase, I went to the store and was disappointed to find that the swimsuits were no longer available.
Nothing happened in high school other than I used to like to see other boys changing for gym class.  I like to see them in their white briefs more than seeing them naked.  It wasn't until I was in my early 20s that it clicked and I hooked up with another young guy.
A year later, I became friends with a guy from work.  Eventually we became lovers as well as best friends, and we had it going on for 6 years.  It's nice for me to think back to how innocent I was at the start and how I tuned into my sexuality as the years went by.
