Is a husband permitted to seek separation from his wife due to her problem of sexual frigidity?

The wife's sexual frigidity does not grant the husband the option to annul the marriage contract. The husband is advised to hold onto his wife if she fulfills his rights and he finds no fault in her character, religion, or any shortcomings in their companionship, for divorce is the most hateful of lawful things to Allah. If there is a need for divorce, there is no harm, but the wife's sexual frigidity is not a necessity for divorce; because it can be treated or by marrying another while retaining her.
