Born again devoted daughter of God. But I deeply struggle with lust, porn, masturbation, and fornication.

29F. Never married no kids. So I’m a newly devoted to walking with god, reading the Bible, even studying to be a daughter of the king. I always struggle when im by myself reading… it’s like my mind wonders and I feel an urge to masturbate. I’ve sinned a lot in the past, had multiple sexual relationships with men but obviously it was lust based. I know in the Bible I’m not supposed to have sex until married and watching porn and masturbation is a sin. I’ve prayed to have this spirit of lust leave my body but the devil creeps in and tempts me to watch porn and masturbate. I need some helpful advice that will help me get rid of these random urges when I have an idle mind. Thank you.
