Fanny Fern: Critics: Sexual Inuendo?

I absolutely have grown to love Fanny Fern over the past few years.  The more I read "Critics," I cannot help but feel that it has a sexual undertone.  Fern states, "I never new an editor to nib his pen with a knife as sharp as his temper, and write a scathing criticism on a book, because the authoress had declined contributing to his paper " (2104).  It seems that the man or critic  in this excerpt has went to find another woman to fulfill his sexual needs, or to nib his pen at, because his wife, or authoress, has stopped contributing to his sexual desires.  Fern also uses terminology such as taper fingers, and porcupine quills, which closely resembles the male genitalia.  She refers to the new mistress as "poor" and a "self-reliant wretch," while she refers to the wife as a "fashionable authoress [whom] once laved his toadying temples."  I feel that Fern is going beyond literature and making a statement more about how men men satisfy their sexual needs in reality.
