Something like that -- I think how it went down was that pubescent boys were "adopted" by older males for a few years to "show them how to be men", which not-so-much involved butt-fucking but mainly rubbing ones off between the thighs of the teenage boy from time to time and heavy petting style stuff like that along with birds and bees type talks to "prepare" them for having wives..... pretty creepy stuff those Greeks were into, they all touched little boys.... Plato, Socrates, Homer, all of em.....
And if anyone is wondering why how come I know so much about this its because we read ancient greek translations about it in a required humanities class in college back in the day -- I'm NOT some kind of self-taught "history of butt-fucking and paedofilia" expert....
