In the school changing room

I went to an all boys school in the late fifties to early sixties .I did`nt do much if anything in the way of P E or games due to poor health . But I was still expected to join the boys of my class for these activities , both in the changing rooms and in the gym hall mainly as an observer .
It was in the changing rooms that I would have to be be seated as the boys undressed before me . As underpants were not allowed under P E shorts ,the boys had to get their underpants off and put on their shorts ,along with a t shirt and plimpsolls .
After sports or pe it was back into the changing room to have a compulsory shower .
So another opportunity to see their bare bottoms cocks and balls .
Several of the boys would ask me to look after their watches as they began to get undressed .
I was happy to oblige ,returning them after their shower when they were fully dressed again .
This was during ages thirteen to fifteen .
My interest in what I was able to observe was not from the start of this arrangement but it just grew the more I
sat in twice weekly for these occasions
