Book XII, Epigram 55 (Ker)

He who bids you, girls, give your favours for nothing, is a most foolish and impudent fellow. Do not give them for nothing, kiss for nothing. This Aegle refuses, this in her greed she sells. But let her sell it: how precious is a good kiss! This she sells, I say, and for no small plunder too; she asks for either a pound of Cosmian unguent, or four times two gold coins of the new mintage, that her kisses may not be silent ones or grudgingly given, that she may not with shut lips deny their approach. Yet this one thing she does graciously; Aegle, who refuses to give a kiss, a single kiss, for nothing, does not refuse to for nothing.
