In my classical studies class (high school) we are learning about Alexander the Great. I understand that Alexander was tutored by Aristotle, yet some of the material we have received mention a possible intimate relationship between Alexander and his tutor. I have also read from the resources given that young men who are training to be a part of the military were often tutored by older men who had to "win their affections". I am not entirely sure where the sources are from (possibly J.R. Hamilton). I would also like to know about the perception of homosexuality compared between Ancient Greece and today.
Pederasty was seen as a civic duty by the Greeks, since in its essence it was a relationship between a superior and an inferior (erastes and eromenos) not only in the body but in the mind as well, so the boys would be taught manhood in a way, but you also need to consider that Greek society was deeply misogynistic and the company of women was seen negatively by many when it didn't have the specific purpose of reproduction. When it comes to homosexuality there was a double standard as showcased in the myth attributed to Aristophanes by Plato in the symposium: male/male relationships are the best form of relationship, male/female ones are not as good but not condemned for obvious reasons and female/female ones are ungodly and technically condemned, but in practice it was acceptable as long as both women weren't married as shown by the success of Sappho who had a sort of pederastic relationship with her students.
