Men advanced in age, whose member will no longer obey their will, are more inclined to irrumate than others. To this circumstance the passage in Martial, IV., 50, refers:
“No man is too old to irrumate.”
XI., 47:
“Gain the heights; there your old member will revive.”
And III., 75:
“Your mentula, Lupercus, has long ceased to stiffen; nevertheless, in your folly you strive to make it rise. You are fain now to corrupt pure lips for gold; but even so your Venus is stimulated in vain.”
For this reason irrumators are less feared by married men. Thus Martial dealt more lightly with Lupus, whom he had surprised while irrumating his Polla, in the passage (X., 40) quoted previously. The husband of Glycera, if so be that she had one, also need not have feared that Lupercus would do duty for him, Martial, XI., 41:
“Lupercus loves the beautiful Glycera; he is her lord and master, and he alone. He was complaining bitterly he had not loved her for a month; Aelianus asked the reason,—he replied Glycera had the toothache.”
Lepidinius, in the Hermaphroditus (I., 13), is of opinion, that anyone who has once irrumated can never get rid or renounce the habit. I must leave it to experts to decide upon this. So also thinks Aloysia Sigaea: “Such as have once tasted it, are mad after this pleasure.” (Dial. VII.)
No wonder that after fellation, the mouth has to be washed out with water. Martial alludes to this, II., 50;
