After William's return, he and Philippa for a time lived contentedly with each other, producing a further five daughters, and a son, Raymond. She also ignored the Duke's sexual boasting in song and talk, instead concentrating on religion (in particular the Abbey of Fontevrault, of which she remained a keen sponsor), especially the teachings of its founder, who preached the superiority of women over men. Her obsession with a doctrine considered offensive by many men of that time, combined with William's growing dissatisfaction with her, and his teasing of her (claiming to be founding an abbey of prostitutes), led to discord in the marriage.
