In case any of you were wondering:
Certain words were considered only for men to use, and similarly only for women. So, when you find a fabliau where women are not using their deemed words, things get fun real quick.
So, women were only allowed to refer to a man's you know as a yard. (cue I roll, I know).
Men could call it a pintel or a tarse.
Other fun fact, the F-word is older than you think, but is not the only word that is regarded with such severity. There are others on the same echelon.
For instance: swived. to swivel. was considered equally as bad. Though, the f-word, is far punchier.
Stop me, or I'll keep going. LOL.
