When I was a kid in the mid -to-late 50's, Saturday morning open swim at the YMCA for boys 8-16 was naked only, and early on I loved getting to see the older kids with their bigger cocks and pubic hair! By the time I was one of the 'older' kids I loved seeing the younger ones look at my package. Often in the pool I'd sport a boner and sort of 'bump' into some of 'em with it!
Often when the pool would be crowded some of the younger ones would dare to make a grab at mine, and I'd kindly reciprocate by giving theirs a little grab. Innocent water play we figured. To be honest, I'd often jack off later thinking about 'encounters'.
Any other guys have early "Y" times like that?
