Xenophon, Hiero 1.29-30
“In his sexual relationships with boyfriends, much more even than those activities for having children, a tyrant falls short of happiness. Certainly, we all understand that sexual pleasures are much increased under the influence of desire. But desire is certainly least willing to arise in a tyrant.
For lust does not take pleasure in aiming for things ready at hand, but instead for those things that are only hoped for. For this reason, a man who knows nothing of thirst gets no pleasure from drinking; and the man untested by desire is inexperienced of the sweetest sexual delights”
Ἐν δὲ τοῖς παιδικοῖς ἀφροδισίοις ἔτι αὖ πολὺ μᾶλλον ἢ ἐν τοῖς τεκνοποιοῖς μειονεκτεῖ τῶν εὐφροσυνῶν ὁ τύραννος. ὅτι μὲν γὰρ τὰ μετ᾿ ἔρωτος ἀφροδίσια πολὺ διαφερόντως εὐφραίνει, πάντες δήπου ἐπιστάμεθα. ὁ δὲ ἔρως πολὺ αὖ ἐθέλει ἥκιστα τῷ τυράννῳ ἐγγίγνεσθαι. οὐ γὰρ τῶν ἑτοίμων ἥδεται ὁ ἔρως ἐφιέμενος, ἀλλὰ τῶν ἐλπιζομένων. ὥσπερ οὖν οὐκ ἄν τις ἄπειρος ὢν δίψους τοῦ πιεῖν ἀπολαύοι, οὕτω καὶ ὁ ἄπειρος ὢν ἔρωτος ἄπειρός ἐστι τῶν ἡδίστων ἀφροδισίων.
