Catullus 69

Do not wonder, Rufus, why no woman wants to place her soft thigh under you, not if you loosen that one with a gift of a fine garment or luxuries of transparent stone. A certain evil tale hurts you, in which it is said a savage goat lives under the vale of your upper arms. Everyone fears this, and no wonder: for the beast is very evil, and the sort with which a pretty girl does not lie. Therefore either kill the harsh curse of noses or cease to wonder why they flee.
