What should a 17-year-old do, who feels love towards women and wishes to marry, while he is in a critical stage of his high school studies, where he deliberately looks?

A Muslim must comply with the command of Allah the Almighty and His Messenger, and he must stop looking at what Allah has forbidden, for persisting in that is prohibited and may lead to what is worse. He must repent and turn to Allah and ask Him for chastity. Marriage is recommended for those who can afford it, and for those who cannot, they should fast. One must seek help through patience and prayer, and increase in reciting the Qur’an and seeking forgiveness.
