I was a late developer - at two boys-only boarding schools. I wasn't yet 14 by the time I went to high school. It was a school divided into 'houses' that competed against each other in every conceivable way - even the house dramatic presentations were rated. But of course, most of the contests were physical and ranged from team sports (we played cricket, hockey (known as armed football) and rugby) and all had standard performance levels that were age-related.
For a late bloomer, this meant three excruciating years of being the guy no one wanted on their team. Only when I was nearly 17 was I able to earn ANY standard points for my house, except for cross country running, which requires courage even before development and stamina. This is all, all sex-related, too. At my first school, some of my contemporaries began puberty very early, and were the wonder of the school for their full bushes, adult cocks and balls - and their masturbatory prowess. It was a sought-after privilege to be invited to wank with one of these great ones and to gaze on the cum geysers they shot into the air- Wow! But woe betide anyone, pre- or post-puberty, who had an erection in the communal showers!. You couldn't avoid the other guys because hot water was strictly rationed, so we all had to shower together. Except, of course, that the juniors were pushed out of the stream whenever possible by their seniors.
At high school, not much changed except the perception of the undeveloped (especially if he were artistic, an academic, or (worst of all) musical. All of these were considered as indicators of likely homosexuality (the word gay still meant light-hearted fun). And there was nasty stigma attached to that. I was bullied, being both academic and musical. In my maturity, I understand that probably most of us were anxious about our sexuality, and projected this on to others. After all, we never saw a girl for the whole term! Would we really find them attractive? But actually being caught masturbating was the worst disaster imaginable despite the fact that, of course, we were all doing it. You would be greeted with, 'Hey wanker (specific gesture), sies, man!' It's hard to translate that Afrikaans word, but you don't want to hear it about yourself.
Well, the circle jerks went on among friends who hadn't yet, or were still developing body hair, bigger penises and balls and deeper voices (I went from treble to bass over one holiday) t mean? Nothing, apparently, though I could never tell a soul! Cows aren't really my thing!. I am still married to the wife I chose and we now, after 51 years, have five grandchildren.
Some us probably were gay - one was expelled for indiscreet anal sex. My persecution persisted even after my genitals developed - because now I was bigger than anyone else, and the 'main men' pretended to be disgusted by my large and uncut cock. Of course, they were really envious, but I didn't know that; it didn't help my ego at all.
Over all, I agree with Maurice Chevalier in 'Gigi.' I'm glad I'm not young any more.
