Does not the fact that a woman cannot be forced into certain types of pleasure, because they violate sound human nature, contradict the obligation of a wife to obey her husband unless he commands her to commit a sin?

A wife must obey her husband in matters that do not involve disobedience [to Allah], and this applies to what is considered customary (ma'ruf).

Thus, obedience to the husband is not obligatory if the enjoyment is forbidden, such as anal intercourse or intercourse during menstruation, or if it results in harm to the wife, like licking his semen. These actions are not considered customary (ma'ruf).

However, if the enjoyment is neither forbidden nor harmful, then the wife must obey her husband in it, based on the principle of permissibility (ibahah).
