Is the wife legally obliged to initiate flirtation with her husband if he demands it, and is her failure to do so considered a valid reason for him to marry another?

There is no evidence indicating that a woman is obligated to flirt with her husband. What has been reported is that the wife is obliged to provide her husband with the pleasure he is accustomed to receiving from her. A woman is commanded to obey her husband in what is good and lawful. If a husband commands his wife to flirt with him, then this might be something she must obey him in, as long as he does not command a sin or something unusual. It is advisable for a wife to be a good partner to her husband and to obey him in matters of conjugal relations, as long as he does not command a sin.
