Here's other times when I SHOULD have known I was gay, but didn't take the strong hint. About 8 of my school friends were camping on an island in a river, that we reached by rowboats. At night we had a campfire, and some of the guys stripped down to their underwear to be "Indians" whooping around the fire. Stupid, I know, but we were all about 13.
Seeing those guys in nothing but their plain cotton tighty-whities (which were the only type of undies most of us boys wore back then) was an enormous turn-on, as I lay watching in my sleeping bag. And I got hard. And started stroking myself.
Not sure why, but I pulled open my sleeping bag and asked the others if they knew how to jerk themselves. I think most, if not all, said they did not. So I gave them a demonstration.
As I came close to cumming I got up, to shoot my load into the fire. It caused quite a sensation, but no criticism, at least not to my face. Such exhibitionism was new to me, and I do nothing like it today. But I was so incredibly aroused being with these near-naked guys it was irresistible to me.
Nobody did anything 1/1 with me that night. The next day they went skinny dipping in the river (despite being told it was polluted), but not me. I couldn't control a raging hardon, seeing them all naked. I used the dirty water as my excuse. Only a few of them had begun to get body hair, I was the most developed, and some still had little boys dicks. Especially "Harold" which really embarrassed and bothered him.
About 7 months later it was winter during a heavy snow fall. And mostly this same band of classmates got together to go sledding together. We got good & wet, and shivering, finishing the day back in the basement family room of one of the guys.
His mother ordered us to strip off our wet things, which she would hang inside and also put in the dryer, and left us towels, while going to make hot chocolate. What a difference 7 months makes at that age! These guys now had full bushes, and their dicks a decent size. And we poked fun at an Irish red head, because his pubes were as flaming red as his head, first time I think any of us had seen him nude since the summer. While once again I had to conceal my hardon.
Suddenly his mother barged back in without warning, carrying dry clothes for her son, while we were in various states of undress. We hastily grabbed towels and whatever clothes were handy.
But the son stood there, completely nude and unconcerned, with the recently matured body of a young man, while he accepted & donned the fresh things from her. The rest of us were a bit surprised by that, not something we did with our own mothers even in that era.
Back home later that evening I jacked off to the memory of our all being naked together (we hadn't begun HS yet with gym locker rooms and gang showers, and I hadn't swum nude at the Y for years, so not a routine occurrence).
But even that didn't raise flags for me that I was gay (we actually said queer, fairy & homo), because as I've said before I lacked the other stereotypical prerequisites for being queer in those days. So I honestly didn't know what I was, but I recognized something was going on, and it was different.
