When the masturbation is done by the loan of another person’s hand, it is possible that the pleasure is participated on the part of the agent.
It forms part of the business of a courtesan to be clever with her fingers; a languid member may by their use be invigorated. The inertness of the virile member may be caused by the inconveniences of age, and this either on the part of the woman, as in Martial, VI., 23:
“You require my penis, Lesbia, to be ever in erection for you; believe me a man’s member is not like a finger. True, you strive to excite me with hands and tender words, but your face is a stubborn fact and counteracts all your efforts.”
and again in the same author, XI., 30:
“When you set your old hand the task of rousing my member, your thumb, my Phyllis, will but strangle me.”
or of the man, Martial, XI., 47:
“Only in dreams you get stiff[[98]], Maevius, and your verge begins to make water right onto your own feet; in vain your wearied fingers ply your wrinkled member,—rouse it as you may, it will not raise its drooping head.”[[99]]
Aristophanes in the Wasps, 735-38:
“Yes, I will nurse him and get him all that is wanted for an old man: beef broth to lap, soft wool, and a rug to keep him warm, and a courtesan to rub his member and his loins...”
The same author, ibid., v. 1334, 35:
