What is the guidance and advice for dealing with increased sexual desire despite being married, and its impact on daily life and worship, along with attempts to struggle against the self and Satan?

You should take the initiative to protect your chastity by being frank with your wife about your needs, or by marrying a second wife if you are able, or by fasting, which is a prophetic remedy that helps lower the gaze and guard one's chastity. You must also strive against your own self to abandon bad thoughts, refrain from searching for provocative titles on search engines, and supplicate to Allah to avert evil and indecency from you. You should know that the responsibility and effort in raising children entail a great reward, and that easy pleasures from the unlawful have bitter consequences, for "there is no good in a pleasure after which is the Fire." Increase your listening to admonitory lectures and reading books of spiritual edification.
