What was the main reason behind the wife of Al-Aziz inviting Yusuf (Joseph), peace be upon him, to commit adultery?

The exegetes mentioned that the wife of Al-Aziz was exceedingly beautiful, and her husband did not approach women, while Yusuf (peace be upon him) was exceptionally handsome. This is what drove her to commit the indecency. Yusuf married the wife of Al-Aziz after her husband's death and asked her, "Is this not better than what you desired?" She replied, "O truthful one, do not blame me, for I was a beautiful, tender woman of royalty and worldly possessions, and my companion did not approach women. And I was as Allah made you in your beauty and appearance, as you saw." They claimed that she was found to be a virgin.
