Honeypot, I recently contemplated posting a question about straight people who have had same-sex experiences at some point. So, I am glad you did.
During puberty, when relationships with girls were non-existent or very timid, several of us boys "fooled around." We mostly talked, but occasionally masturbated together, but not each other. I had one experience each, with two different boys, of oral sex and anal sex. Puberty visited me quite early and these events occurred when I was eleven years old.
In the oral sex instance, a friend, who was spending the night with me, and I tentatively sucked each other's dicks. Neither him doing me, nor me doing him, lasted very long or went very far, but we did briefly take each other's dicks in our mouths and give them a little suck. Taking another guy's dick in my mouth seemed like something unimaginably bizarre! No great pleasure was derived by either of us, but it was an experiment.
The anal sex experiment happened during the day, when a different friend was at my house, and no one else was at home. We decided to see what it felt like to butt fuck each other. What we REALLY wondered was what it would feel like to fuck a girl. The common term then for butt fucking was corn-holing. Gross! Anyway, he lubed-up his penis and, with me lying face-down on my bed, he attempted to enter me. I tolerated as much as I could stand, but just could not bear the pain of him penetrating me. In fact, to this day, his erect penis was the largest I have ever seen personally. After that failed attempt, it was my turn, and he lay face-down on my bed while I lubed-up my smaller penis. He tolerated my penetration and I fucked him for several moments. We both agreed that it felt good. I still wondered if it felt anything like fucking a pussy. It was a LONG time before I learned that it did not.
These were, as described, experiments. They were experiments between boys because we were having powerful urges and were curious, but experimenting with girls was not an option. There was no male-male attraction. So, were these acts homosexual? I don't know. I don't care. They were learning experiences.
