I am looking for a story I read here a few years ago. The page was in PDF format, and the story was about a boy who had a girlfriend. All I could remember was that they tried to have sex one day but they were stopped when the mother came home? And he met this boy (the girl's cousin, maybe?) and realized that he might be gay after all, and they had sex when the boy stayed overnight at his house. Please let me know if you know this short story
