Taking showers with other guys.
Daniel Martin
Weird, I'm 30 and showers were still mandatory when I took physical education in middle school. Maybe it was because I was living in Hawaii at the time, which is culturally different in many ways from the mainland US. This was eighth grade; boys were 13-14 so a really wide range of physical development in the locker room.
I was mortified about getting naked around all these guys whom I found attractive, so made excuses, feigned being sick and avoided PE class for a couple weeks, until the teacher threatened, kindly yet firmly, to contact my parents if I didn't show up to PE and take a shower with the rest of the boys the following week. As my father was an abusive alcoholic who hated my emergent homosexuality, I reluctantly went along with it.
That first time back in the locker room, when all the other boys were casually pulling off their clothes, japing and horsing around, was pure torment for me. I felt dizzy and nauseous (which I suppose was ironic considering I had been pretending to be indisposed) and was dragging my feet with heading to the showers. As luck would have it, my crush lagged behind as everyone else dispersed and struck up a conversation. He was a Japanese athlete with a room-lighting smile, a total local boy. He asked me why I'd been skipping class; I lied and said I'd been sick, and asked him whether he believed me. He paused and asked me if I was feeling okay again. Without technically lying, I looked into his eyes and said I was feeling a little queasy. I know, MARY!
Anyway, him taking an interest bolstered my confidence, and I hurried to get undressed as he went to join the other boys, stark naked. I stared at his small, pert ass as he walked off. Thankfully, my crippling fear of being outed kept my cock soft, and I got to the showers and made it through the rest of the year unscathed.
What I found funny was that the "straight" boys were way more interested in looking at my penis than I was at theirs. Especially the delicate flowers who covered their private parts with their hands for the entire school year; these were the ones who were the most curious about the cocks of other boys. After one glance at most guys I was satisfied, with one notable exception. There was a quiet Hawaiian guy named Jonah in our year to whom I'd paid little attention up to that point. But man, did he have a whale. He caught me staring at his long brown cock and fat balls one time and shook his hips to bounce them back and forth. When I looked up at him he winked and grinned. Nothing came of it other than masturbatory fantasies for the rest of middle school, but I wonder if he ended up being gay like me.
