Perhaps this is punishment for homosexual men who have no inclination to marry:
Athenaeus 13.2
"But Clearchus of Soli, in his treatise On Proverbs, says,- "In Lacedemmon the women, on a certain festival, drag the unmarried men to an altar, and then thrash them; in order that, for the purpose of avoiding the insult of such treatment, they may become more affectionate, and in due season may turn their thoughts to marriage."
And later on he writes:
"[4.] But Heracles is the man who appears to have had more wives than any one else, for he was very much addicted to women; and he had them in turn, like a soldier, and a man employed at different times in different countries. And by them he had also a great multitude of children. For, in one week, as Herodorus relates, he relieved the fifty daughters of Thestius of their virginity."
What a delicate translation.
