Is the wife sinful if she dislikes intercourse with her husband who has lost his sexual ability due to illness and neglects her after satisfying his needs, which has led to her aversion towards him, especially since he continues to use his hand to satisfy her, causing her pain?

A wife must obey her husband in matters of enjoyment, and it is not permissible for her to refuse unless there is a reason such as illness, menstruation, or an obligatory fast. Lack of desire is not an excuse. However, she is not obligated to obey him in anything that harms her or exceeds the bounds of conventional enjoyment.
