What is the ruling on the marriage of a fiancé who suffers from sexual dysfunction and wishes to keep his fiancée, yet fears he will not be able to fulfill her marital rights?

If you inform your fiancée of your sexual dysfunction or something similar, there is no harm in marrying her, as she can waive her right to sexual intercourse. However, if you are asking for advice, we recommend that you seek treatment for your condition. If you are cured, then marry her. If you are not cured and the girl is young, we advise you to release her and guide her to marry someone else to avoid discord and for her to live a normal life. You, on the other hand, can look for a woman who has despaired of marriage or who does not desire sexual intercourse, while clearly stating your condition to her before marriage.
