By the time I started high school, I was about 1 year into puberty. We were all required to take "gym". It was good for us. A lot of the time we just ran around the track. We tried rope climbing and touch football, etc. Afterward, however, we were expected to go through the shower. There were boys of all developmental stages going through the shower. A few had not hit puberty yet. And then there were some who had a great deal of hair. One guy was engaged to get married. He was highly developed ! wink
