Does foreplay with one's wife after the legitimate marriage contract lead to nocturnal emission, and is it permissible for a man in this situation to practice masturbation?

Masturbation is forbidden (haram), and it is not permissible to practice it for the sake of pain unless the pain is severe and unbearable, and masturbation is determined to be the only means of alleviating this pain, and no other permissible method is available to دفع it. It is recommended to hasten marriage, as it is one of the means of treatment.
