That Wife of Bath states that Jankyn, her fifth husband, was her favorite—largely because he was so good in bed.
She proposes to him that they get married after her fourth husband dies, and he agrees.
Jankyn is different from her other husbands. He is younger than she is and poor. He is educated and refuses to let the Wife of Bath dominate him. Because of his education, he enjoys reading antifeminist writings at night. She gets so angry at him about these misogynist works that she tears out three pages of his book and throws them in the fire. This is more serious than doing so today, as books then were still hand copied and thus very expensive.
Although he beats her, once knocking her to the ground so that she faints, the Wife of Bath states that she eventually is able to totally dominate him.
Of course, we have to take everything the Wife of Bath says with a grain of salt, but the couple seems to have thrived in their stormy, quarrelsome relationship.
