All praise is due to Allah alone, and may the Salah and Salam of Allah be upon our Prophet Muhammad, his family and his companions. To answer your question, we say while seeking all the success from Allah: It is impermissible to watch pornography with the justification that it is for having stimulation or arousal to be able to intercourse. This is because doing so includes watching that which is unlawful to watch and seeing the body parts of others that one must not look at. Not to mention, it makes one to see adultery and fornication, which are despised by Allah and His Messenger (may the Salah and Salam of Allah be upon him). For all these reasons, it is forbidden to watch pornography at all cases. As for reading pornographic stories, while they are less evil than porn movies and images, they are still considered from the steps of Shaytan because such stories either narrate stories about adulterers, which is a forbidden act, or narrate stories of spouses who shared with others their intimate life, which is also forbidden. Abu Sa’id al-Khudri (may Allah be pleased with him) narrated that the Prophet (may the Salah and Salam of Allah be upon him) said: “Among the most evil of people in the sight of Allah on the Day of Judgment is the man who goes to his wife for intimacy and she comes to him for intimacy, but then he divulges what she did.'' Reported by Muslim (1437) Aside from the above mentioned overriding reasons, resorting to this means will compromise your shyness, lure you to indulge in evil, and the result will be counterproductive i.e. it will make the husband less attracted to his wife and the wife less attracted to her husband.
