I just had to share this, it was very amusing.
Franklin had a friend who did not want to get married, but was battling with urges and lustful inclinations for the opposite sex. In the letter which follows, Franklin first advises the friend that the best solution for his urges is marriage. However, since he knows the friend will not take that advice, Franklin goes on to suggest that his friend have sexual affairs with old women. We know from the context that he is suggesting women over 45 years of age (see #3). His words about putting a basket over her head or turning out the light (see #5) illustrate an aspect of Franklin’s character which is seldom exposed.
Adding this to his numerous accomplishments, skills, and interests, I think it was safe to assume that he was definitely a bad-ass during his time!
