Is it permissible to look at young men and lewd pictures?

What you are experiencing is due to weakness of faith and a lack of awareness of Allah’s constant watch and the Last Day. Whoever is mindful of these will not corrupt themselves with desires and disobey Allah’s command to lower the gaze and guard their chastity. Therefore, you must repent to Allah and lower your gaze from what displeases Him, for lewd pictures and websites are forbidden by Islamic law due to the vice they lead to.
