Book XI, Epigram 22 (Ker)

That with your hard mouth you rub the soft lips of white-cheeked Galaesus, that you consort with a naked Ganymede, 'tis too much — who denies it? — but let that be enough; at least refrain from waking passions with lascivious hand. Towards beardless boys this is a greater sinner than your yard, and your fingers create and hasten manhood. Thence comes a goatish odour, and quick-springing hair, and a beard, a wonder to mothers, and baths in broad day are displeasing. Nature has separated the male: one part has been produced for girls, one for men. Use your own part.
