In a Classical (Western) education that involved learning Greek and Latin and reading works in the original, were texts involving Ancient Greek and Roman homosexuality censored?

Maybe always framed as sinful from a Christian perspective? Ignored unless referenced to in a Biblical studies lecture? Perhaps everything was open and known, but no one dared speak about it? Could the views at the time have been more akin to Achilles and Patroclus were just best bros and no decent person would ever consider anything…beyond…that? Or alternatively, “they were Greek, so naturally they were sodomites, the lot of them, and in their wickedness…”?

In high school English class we read A Separate Peace by John Knowles. Someone from a previous year had written “Gene is gay!” in a classmate’s copy. Do we have schoolboy marginalia from hundreds of years ago commenting on the Ancient Greeks and Romans?

Thank you.
