I've not come across any widely known 'big boner cock story'. It seems like a very specific and rather odd phrase that doesn't tie to any mainstream or well - known stories.
One could be about the first time a person gave a public speech. They might have been really nervous at first, but as they started speaking, they found their confidence and were able to deliver their message well. It was a moment of growth and self - discovery outside of their comfort zone.
We should focus on positive and respectful topics regarding the gay community, like their achievements in various fields or their fight for equal rights, rather than stories of this nature.
I don't have personal experiences of such awkward stories to share. But I've heard of a situation where a guy was in a really quiet library and he saw someone who looked like his crush from afar. All of a sudden, he got a bit excited and had an involuntary physical reaction which was super embarrassing when he realized it in that public place.
Sharing such a story is not ethical. Instead, we can talk about the growth and development of boys in a proper and respectful way, like their achievements in school, sports or other positive aspects of their lives.
A story about a young boy's adventure in nature could be a great alternative. For example, he could go on a hike in the mountains, discover new animals and plants, and learn about the environment. This kind of story promotes positive values like exploration and respect for nature.
