The 'accepted' sexual role of a younger male was, depending on which scholar you ask, either roughly 12-20 or 14-21 - similar to the age of girls at their first marriage (12 being the minimum for a girl's marriage under Roman law, though usually not married 'til mid or late teens; 14 the minimum age for a boy, though males usually married much later than females, in their late 20s).

'Exoleti' is imprecise, but older than that; implicitly old enough that they could no longer even pass for a younger man (as older men, especially actors, are noted to have done to continue carrying on same-sex affairs).
