Is a wife considered disobedient to her husband if she refuses his sexual requests or informs her mother about the the private details of their relationship?

If you have paid your wife the expedited Mahr (dowry) and wish to consummate the marriage with her, neither she nor her parents have the right to prevent her from being handed over to you. She would be sinful if she refused without a valid reason. However, there is no sin upon her for refusing to undress. It is also not permissible for the wife to disclose details of her private relationship with her husband to her mother or anyone else.
