Are the mentioned physical symptoms—such as fever, pain, and general weakness, which worsen after masturbation or during erection—normal and indicative of an illness? Is there a cure for this condition, and is it permissible to marry with the fear of falling short in marital duties?

Masturbation is forbidden, and repentance from it is obligatory. This repentance involves abstaining from it, regretting it, and resolving not to return to it. It is recommended to consult a doctor for treatment. There is no objection to marriage despite sexual weakness, as long as it is not definitively established that one is unable to satisfy the wife. It is not necessary to inform the fiancée about this as long as intercourse is possible.
