 Even though the gender that one was erotically attracted to (at any specific time, given the assumption that persons will likely be attracted to persons of both sexes) was not important, other issues were salient, such as whether one exercised moderation. Status concerns were also of the highest importance. Given that only free men had full status, women and male slaves were not problematic sexual partners. Sex between freemen, however, was problematic for status. The central distinction in ancient Greek sexual relations was between taking an active or insertive role, versus a passive or penetrated one. The passive role was acceptable only for inferiors, such as women, slaves, or male youths who were not yet citizens. Hence the cultural ideal of a same-sex relationship was between an older man, probably in his 20s or 30s, known as the erastes, and a boy whose beard had not yet begun to grow, the eromenos or paidika. In this relationship there was courtship ritual, involving gifts (such as a rooster), and other norms. The erastes had to show that he had nobler interests in the boy, rather than a purely sexual concern. The boy was not to submit too easily, and if pursued by more than one man, was to show discretion and pick the more noble one. There is also evidence that penetration was often avoided by having the erastes face his beloved and place his penis between the thighs of the eromenos, which is known as intercrural sex. The relationship was to be temporary and should end upon the boy reaching adulthood (Dover, 1989). To continue in a submissive role even while one should be an equal citizen was considered troubling, although there certainly were many adult male same-sex relationships that were noted and not strongly stigmatized. While the passive role was thus seen as problematic, to be attracted to men was often taken as a sign of masculinity. Greek gods, such as Zeus, had stories of same-sex exploits attributed to them, as did other key figures in Greek myth and literature, such as Achilles and Hercules. Plato, in the Symposium, argues for an army to be comprised of same-sex lovers. Thebes did form such a regiment, the Sacred Band of Thebes, formed of 500 soldiers. They were renowned in the ancient world for their valor in battle.
