Laconian Assmen and Theseus (Photius 192.12)

“Laconian Ass-man”: Cleinias, had anal-sex, in the Laconian style. They call intercourse with boyfriends “to act like a Laconian”. This is how Theseus had sex with Helen, according to Aristarchus.

Κυσολάκων: ὁ Κλεινίας ὁ τωῖ κυσωῖ Λακωνίζων· τὸ δὲ τοῖς παιδικοῖς χρῆσθαι Λακωνίζειν λέγουσιν· ᾿Eλένηι γὰρ Θησεὺς οὕτως ἐχρήσατο, ὡς Ἀρίσταρχος.

Some texts have Μελαίνηι instead of ᾿Eλένηι. Some have ᾿Αριστοτέλης instead of Ἀρίσταρχος
