From the excellent Letters of Note blog, a letter from Ben Franklin written in 1875 to an unknown (but presumably younger) friend about the pluses of ye older Women:
Ben Franklin warns his young penpal that he's headed for trouble if he doesn't 'diminish his violent natural Inclinations,' and tells him to find a sugar momma:
4. Because thro’ more Experience, they are more prudent and discreet in conducting an Intrigue to prevent Suspicion. The Commerce with them is therefore safer with regard to your Reputation. And with regard to theirs, if the Affair should happen to be known, considerate People might be rather inclin’d to excuse an old Woman who would kindly take care of a young Man, form his Manners by her good Counsels, and prevent his ruining his Health and Fortune among mercenary Prostitutes.
5. Because in every Animal that walks upright, the Deficiency of the Fluids that fill the Muscles appears first in the highest Part: The Face first grows lank and wrinkled; then the Neck; then the Breast and Arms; the lower Parts continuing to the last as plump as ever: So that covering all above with a Basket, and regarding only what is below the Girdle, it is impossible of two Women to know an old from a young one. And as in the dark all Cats are grey, the Pleasure of corporal Enjoyment with an old Woman is at least equal, and frequently superior, every Knack being by Practice capable of Improvement.
6. Because the Sin is less. The debauching a Virgin may be her Ruin, and make her for Life unhappy.
7. Because the Compunction is less. The having made a young Girl miserable may give you frequent bitter Reflections; none of which can attend the making an old Woman happy.
8. They are so grateful!!
