Should one get married despite having a slight and intermittent sexual dysfunction, and how can this situation be handled in a way that avoids divorce?

Human beings differ in their sexual desire. Some have intense lust, others less so, and some have no desire at all. If there is even a slight desire for marriage, such as a state where one can engage in intercourse even once a month or every two months, then marriage is permissible for him. However, if there is a complete inability to engage in intercourse, the guardian of the fiancée must be informed before the marriage.
