Early 70s, we'd go to the Y, it was well after the era of men only swimming, or swimming nude in public and the Y in our family friendly town was totally co-ed, but the men's locker room had a big open shower room and following dad's example, I took a quick suit on, no soap shower before entering the pool and a fully nude soapy shower after swimming. Most of my dad's generation had done at least 2 years military service, and my dad's was in the navy, so I was raised with the idea that locker room and shower nudity were nothing unusual. I don't remember that I was ever particularly curious or aroused by dad's naked body, but if there were other men or boys showering nude I know that I took lots of furtive glances. I was beginning to sense something was different about me. One of my teenage fantasies was to have a secret room behind a wall with a full view of a men's shower room. I understand that a few such rooms have been discovered behind the grate work over looking women's shower rooms with lawn chairs set up and candy wrappers lying around. Funny story: I remember once being in the showers after a swim with dad, we were alone, I was probably 8 or 9 and just as I was about to de-suit, a little kid of about 3 or 4, all alone, in his suit comes into the shower room, which you had to pass through to get to the pool. Well, being at that age where one is totally unselfconscious, the kid just stops in his tracks and starts openly staring at my soapy naked dad, and me. And I couldn't take my suit off! My dad, totally not caring about this little kid staring says to me "Joe, take your suit off and soap up." And this kid is looking at me with this expression that says "well, aren't you gonna?" and I'm so annoyed, and I can't, I just wash up with my suit on and my dad doesn't press it, he just chalks it up to another of my growing weirdnesses as I was entering that age of ridiculous self-consciousness. It strikes me as so funny now that I was so angry at that little kid for doing openly what I was doing so (I thought) discreetly and if I wasn't beginning that ten year stage of obscene inhibition and self-consciousness, I probably would have been more like "here kid, take a good look!" and happily have given him an eyeful, as I should have.
