Definitely!
My earliest sexual fumblings/experiences with another guy involved the showers of the local pool.
The showers (of the outdoor pool) had individual lockable cubicles and we would get adjoining ones and wank each other off underneath the partition. (We were too young and scared to simply go into one cubicle together, thus risking discovery by unwanted 'neighbours').
Also, the showers of the indoor pool were communal showers but with partitioning walls between them. So we would take opposite ones and drive each other mad by showing each other our hard-ons, quickly turning around when other guys would come in.
Well, we were young, innocent and grew up in a small rural village :smile:
